         2 . The tipping paper of  claim 1 , wherein the carrier material comprises 2-hydroxypropyl-β-cyclodextrin. 
     
     
         3 . The tipping paper of  claim 1 , wherein the fragrance material comprises one or more materials of vanillin and ethyl vanillin. 
     
     
         4 . The tipping paper of  claim 3 , wherein a weight ratio of the vanillin with respect to a total weight of the fragrance material is in a range of about 15% to 25%, and a weight ratio of the ethyl vanillin with respect to the total weight of the fragrance material is in a range of about 5% to 15%. 
     
     
         5 . The tipping paper of  claim 1 , wherein the fragrance carrier is disposed in the tipping paper through a fragrance carrier printing process that uses a fragrance carrier ink including the ethanol, the fragrance material, and the carrier material. 
     
     
         6 . The tipping paper of  claim 5 , wherein a weight ratio of the fragrance material with respect to a total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 1.5%, and a weight ratio of the carrier material with respect to the total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 15%. 
     
     
         7 . The tipping paper of  claim 5 , wherein the fragrance carrier ink further comprises a binder, and a weight ratio of the binder with respect to a total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 15%. 
     
     
         8 . The tipping paper of  claim 7 , wherein the binder is a polymer material that is soluble in ethanol and has a molecular weight in a range of about 3,000 to 20,000 and a glass transition temperature in a range of about 60° C. to 90° C. 
     
     
         9 . The tipping paper of  claim 7 , wherein the fragrance carrier ink further comprises microcapsules, and a weight ratio of the microcapsules with respect to the total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 25%. 
     
     
         10 . The tipping paper of  claim 9 , wherein the weight ratio of the binder with respect to the total weight of the fragrance carrier ink is in a range of about 5% to 10%, and a weight ratio of the microcapsules with respect to the total weight of the fragrance carrier ink is in a range of about 5% to 20%. 
     
     
         11 . The tipping paper of  claim 9 , wherein:
 each of the microcapsules has a diameter in a range of about 1.5 μm to 5.0 μm and includes polyvinyl alcohol (PVA), a fragrance, and a cross-linking agent; and   a content ratio of the PVA and the fragrance included in each microcapsule is in a range of 1:3 to 1:7.   
     
     
         12 . The tipping paper of  claim 5 , wherein the fragrance carrier printing process is performed after an overprint varnish (OPV) process is applied to the tipping paper. 
     
     
         13 . A smoking article comprising:
 a smoking material portion that is wrapped by a smoking material wrapper;   a filter portion in which an upstream end of the filter portion is combined with the smoking material portion and is wrapped by a filter wrapper; and   a tipping paper surrounding at least a partial region of the smoking material portion and a partial region of the filter portion so that the smoking material portion and the filter portion are combined,   wherein the tipping paper comprises a fragrance carrier including a fragrance material and a carrier material, the carrier material including the fragrance material,   the fragrance material included in the carrier material is disseminated from the tipping paper in response to moisture, saliva, or friction, and   the carrier material is a material soluble in ethanol.   
     
     
         14 . A method of producing a tipping paper for smoking articles that surrounds at least a partial region of a smoking material portion and a partial region of a smoking article filter portion so that the smoking material portion and the smoking article filter portion are combined and includes a fragrance material and a carrier material that includes the fragrance material, the method comprising:
 adding the carrier material to ethanol to obtain a first solution and stirring the first solution;   adding the fragrance material to the first solution in which the carrier material is added to the ethanol to obtain a second solution and stirring the second solution;   adding a binder to the second solution, in which the carrier material and the fragrance material are added to the ethanol, to obtain a third solution and stirring the third solution; and   printing the third solution, in which the carrier material, the fragrance material, and the binder are added to the ethanol to be used as a fragrance carrier ink, on the tipping paper.   
     
     
         15 . The method of  claim 14 , wherein the printing the third solution further comprises adding microcapsules to the fragrance carrier ink to obtain a fourth solution and stirring the fourth solution,
 wherein a core of each microcapsule is an ethanol-based fragrance and a shell of each microcapsule is PVA, and   the microcapsules are produced by stirring the ethanol-based fragrance and the PVA at room temperature, adding a cross-linking agent to a fifth solution in which the ethanol-based fragrance and the PVA are stirred and stirring the fifth solution at a temperature higher than or equal to 60° C. and lower than or equal to 100° C., and cooling the fifth solution in which the ethanol-based fragrance, the PVA, and the cross-linking agent are stirred.
