         8 . The fin of  claim 7 , wherein a width of the protruding region is formed to be smaller than a width of the application hole. 
     
     
         9 . (canceled) 
     
     
         10 . The fin of  claim 7 , wherein a lower end of the protruding region is disposed adjacent to the tube insertion hole. 
     
     
         11 . The fin of  claim 7 , wherein with reference to a time point when the tube is inserted into the tube insertion hole, a lower end of the protruding region contacts the tube. 
     
     
         12 . (canceled) 
     
     
         13 . A fin comprising:
 a fin body including a tube insertion hole opened along a first direction being one direction being perpendicular to an upward/downward direction, and configured such that a tube extending along the first direction is inserted thereinto; and   a protrusion part protruding from an edge region being a region of the fin body, which defines the tube insertion hole, in the first direction,   wherein the protrusion part includes:   a protrusion part body;   a first groove formed to be recessed from a first protruding portion being a portion of the protrusion part body, which is located in a second direction being one direction being perpendicular to the first direction and an upward/downward direction, in an opposite direction to the first direction; and   a second groove recessed from a second protruding portion being a portion of the protrusion part body, which is located in an opposite direction to the second direction, in the opposite direction to the first direction.   
     
     
         14 . The fin of  claim 13 , wherein the second groove overlaps the first groove when viewed along the second direction. 
     
     
         15 . The fin of  claim 13 , wherein the first groove is formed to be tapered in an upward/downward direction as it goes in an opposite direction to the first direction. 
     
     
         16 . The fin of  claim 13 , wherein the first groove has a shape corresponding to the second groove. 
     
     
         17 . The fin of  claim 13 , wherein when a region of the first protruding portion, which is located on a lower side, is defined as a lower side region, the first groove is formed in the lower side region. 
     
     
         18 . The fin of  claim 13 , wherein the protruding part further includes:
 a first boss formed to protrude from the first protruding portion in the first direction; and   a second boss formed to protrude from the second protruding portion in the first direction.   
     
     
         19 . The fin of  claim 18 , wherein the first boss is disposed not to match up with the second boss when viewed along the second direction. 
     
     
         20 . The fin of  claim 18 , wherein the first groove is located on a lower side of the first boss. 
     
     
         21 . The fin of  claim 18 , wherein the second groove is located on an upper side of the second boss. 
     
     
         22 . The fin of  claim 18 , wherein the first boss is formed to be tapered in the upward/downward direction as it goes in the first direction. 
     
     
         23 . The fin of  claim 18 , wherein a length of the first boss in the upward/downward direction is greater than a length of the first groove in the upward/downward direction. 
     
     
         24 . The fin of  claim 18 , wherein the first boss has a shape corresponding to that of the second boss. 
     
     
         25 . The fin of  claim 13 , wherein the fin body further includes an application hole disposed on an upper side of the tube insertion hole, communicated with the tube insertion hole, and opened along the first direction. 
     
     
         26 . A heat exchanger comprising:
 a tube extending along a first direction; and   a fin, into which the tube is inserted,   wherein the fin includes:   a fin body including a tube insertion hole, into which the tube is inserted; and   a protrusion part protruding from an edge region being a region of the fin body, which defines the tube insertion hole, in the first direction, and   wherein the protrusion part includes:   a protrusion part body; and   a groove formed to be recessed from the protrusion part body in an opposite direction to the first direction.
