Therefore, it is possible to curb erroneous insertion of the heating blade or the susceptor into the first clearance.
  • the raw material portion includes a pair of inner folded portions that are folded along a first folding line and a second folding line and are located inside the raw material portion and a pair of outer folded portions that are folded along a third folding line located between the first folding line and the second folding line and are located outside the raw material portion, and a size of the second clearance between the first folding line and the second folding line is larger than a size of the second clearance between the first folding line or the second folding line of the pair of inner folded portions and an end portion on an opposite side.
  • the relatively large second clearance is formed between the first folding line and the second folding line, and the heating blade or the susceptor is thus easily inserted into the relatively large part of the second clearance. Therefore, it is possible to curb erroneous insertion of the heating blade or the susceptor into the first clearance.
  • the raw material layer includes a non-tobacco sheet including an aerosol source.
  • a flavor inhaler includes: a heating portion that is configured to heat the raw material portion of the flavor inhaler cartridge according to any of the first to fourteenth aspects; and a battery that is configured to supply power to the heating portion.
