 a first region that overlaps the heating unit in a cross-sectional view orthogonal to the axial direction of the accommodating portion, and 
 a second region that is a region other than the first region, and that is present along the axial direction of the accommodating portion, between an other end of the accommodating portion and an end portion of the heating unit on the other end side, and 
   the grasping portion is provided in the second region.   
     
     
         2 . The flavor inhaler according to  claim 1 , wherein formula (1) and formula (2) are satisfied in relation to a cross-sectional view of a cross section cut along a center axis of the accommodating portion and passing through the grasping portion:
     W 1≥ W 2  (1)
       W 3≥ W 2  (2),
   where, in the formula (1) and the formula (2),
 W1 is a length of the first region in a radial direction, 
 W2 is a length of the second region in the radial direction, and 
 W3 is a length of the smoking article in the radial direction, in the first region. 
   
     
     
         3 . The flavor inhaler according to  claim 2 , wherein the grasping portion is a protruding portion, in the second region, that protrudes toward inside of the accommodating portion. 
     
     
         4 . The flavor inhaler according to  claim 3 , wherein
 a bottom member that forms a bottom portion of the accommodating portion is provided at the other end of the accommodating portion,   the bottom member is formed integrally with or as a separate member from the accommodating portion, and   the protruding portion is provided near the bottom portion.   
     
     
         5 . The flavor inhaler according to  claim 4 , wherein the protruding portion extends from the bottom portion of the accommodating portion toward the one end. 
     
     
         6 . The flavor inhaler according to  claim 5 , wherein the protruding portion includes a sloping portion near an end portion on the one end side of the accommodating portion, the sloping portion sloping farther away from the center axis of the accommodating portion as the one end is neared. 
     
     
         7 . The flavor inhaler according to  claim 3 , wherein the protruding portion includes a pair of ridge portions. 
     
     
         8 . The flavor inhaler according to  claim 7 , wherein the protruding portion slopes more toward the center axis of the accommodating portion, the farther away from the other end of the accommodating portion. 
     
     
         9 . The flavor inhaler according to  claim 1 , wherein, in a cross-sectional view passing through a center axis of the accommodating portion, the grasping portion is provided at a position that is separated from the heating unit along the axial direction of the accommodating portion to the other end side of the accommodating portion. 
     
     
         10 . The flavor inhaler according to  claim 1 , wherein
 the smoking article includes a flavor source-filled portion that is filled with a flavor source, and   the grasping portion grasps the flavor source-filled portion of the smoking article that is housed in the accommodating portion.   
     
     
         11 . A smoking system comprising a smoking article and a flavor inhaler, wherein
 the flavor inhaler includes
 an accommodating portion that includes an opening that allows insertion of the smoking article formed on one end, and that houses the smoking article, 
 a heating unit that is disposed along an axial direction of the accommodating portion, and that heats the smoking article housed in the accommodating portion, and 
 a grasping portion that grasps a side surface of the smoking article housed in the accommodating portion, 
   an inner side surface of the accommodating portion includes
 a first region that overlaps the heating unit in a cross-sectional view orthogonal to the axial direction of the accommodating portion, and 
 a second region that is a region other than the first region, and that is present along the axial direction of the accommodating portion, between an other end of the accommodating portion and an end portion of the heating unit on the other end side, and 
   the grasping portion is provided in the second region.   
     
     
         12 . The smoking system according to  claim 11 , wherein
 the smoking article includes a flavor source-filled portion that is filled with a flavor source, and   the grasping portion of the flavor inhaler grasps the flavor source-filled portion of the smoking article that is housed in the accommodating portion.   
     
     
         13 . The smoking system according to  claim 11 , wherein
 the smoking article includes a conductive member inside a flavor source used for filling,   the heating unit of the flavor inhaler generates a magnetic field that varies over time, and   the conductive member of the smoking article generates heat based on a variation in the magnetic field.
