         11 . The flavor inhaler according to  claim 10 , wherein the first restriction unit includes an inner first restriction unit located inside the tubular unit, and
 wherein the inner first restriction unit and the outer first restriction unit are disposed at positions overlapping each other in the axial direction.   
     
     
         12 . The flavor inhaler according to  claim 11 , wherein a space in the first direction is formed between the inner first restriction unit and the outer first restriction unit, and
 wherein the tubular unit is contained in the space.   
     
     
         13 . The flavor inhaler according to  claim 2 , wherein the tubular unit includes a first end portion, and a second end portion opposite from the first end portion and,
 wherein the first restriction unit is disposed inside or outside at least one of the first end portion or the second end portion of the tubular unit in the first direction.   
     
     
         14 . The flavor inhaler according to  claim 13 , wherein the first restriction unit is disposed inside or outside both the first end portion and the second end portion of the tubular unit in the first direction. 
     
     
         15 . The flavor inhaler according to  claim 1 , wherein the tubular unit includes a base portion and a heat insulation layer provided on an outer peripheral side of the base portion. 
     
     
         16 . The flavor inhaler according to  claim 15 , wherein the holding unit includes a first restriction unit configured to restrict a movement of the tubular unit in the first direction,
 wherein the first restriction unit includes an inner first restriction unit located inside the tubular unit,   wherein the first restriction unit includes an outer first restriction unit located outside the tubular unit,   wherein the inner first restriction unit and the outer first restriction unit are disposed at positions overlapping each other in the axial direction,   wherein a space in the first direction is formed between the inner first restriction unit and the outer first restriction unit,   wherein the tubular unit is contained in the space,   wherein the base portion includes a protrusion portion on one end of the tubular unit, the protrusion portion protruding from the heat insulation layer in the axial direction, and   wherein the protrusion portion is contained in the space.
