 wherein the flavor component is included in an amount of 10 to 40% by weight (wt %) based on a weight of the flavored sheet and the flavored sheet has an enhanced fragrance retention.   
     
     
         2 . The flavored sheet of  claim 1 , wherein the activated carbon is included in an amount of 1 to 10 wt % based on the weight of the flavored sheet. 
     
     
         3 . The flavored sheet of  claim 1 , wherein the flavor component comprises at least one selected from a group consisting of rosemary, eucalyptol, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, white sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, mandarin oil, catechin, grapefruit, caraway, cognac, jasmine, cacao, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander and coffee. 
     
     
         4 . The flavored sheet of  claim 1 , wherein the flavor component comprises menthol. 
     
     
         5 . The flavored sheet of  claim 1 , wherein the flavored sheet comprises a cellulose-based polymer. 
     
     
         6 . The flavored sheet of  claim 5 , wherein the cellulose-based polymer comprises at least one selected from a group consisting of methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, hydroxyethylmethyl cellulose, and agar. 
     
     
         7 . A smoking article filter comprising one or more segments,
 wherein at least one of the one or more segments comprises the flavored sheet of  claim 1 .   
     
     
         8 . The smoking article filter of  claim 7 , wherein
 the smoking article filter comprises a paper pipe, and   the flavored sheet is included in the paper pipe.   
     
     
         9 . A smoking article comprising a tobacco medium portion and a filter portion, wherein
 the filter portion comprises a flavored sheet comprising a flavor component and activated carbon, and   the flavor component is included in an amount of 10 to 40% by weight (wt %) based on a weight of the flavored sheet.   
     
     
         10 . The smoking article of  claim 9 , wherein the activated carbon is included in an amount of 1 to 10 wt % based on the weight of the flavored sheet. 
     
     
         11 . The smoking article of  claim 9 , wherein the smoking article is a combustion-type cigarette or a non-combustion-type electronic cigarette. 
     
     
         12 . A method of manufacturing the flavored sheet of  claim 1 , the method comprising:
 step a) of mixing water and a cellulose-based polymer;   step b) of mixing alcohol with a flavor component and activated carbon;   step c) of mixing solutions obtained in steps a) and b) with each other and pouring and spreading the mixed solutions; and   step d) of performing drying at a temperature of 40 to 70° C.
