- the first sheet 37a, the second sheet 37b, and the third sheet 37c are formed by laminating the base material layer 31 and the raw material layer 32, and have a crease F1. Further, the first sheet 37a, the second sheet 37b and the third sheet 37c are arranged so as to face each other in the thickness direction, and the second sheet 37b and the third sheet 37c are arranged adjacent to each other in the width direction.
- a first gap 34 is formed between the first sheet 37a and the second sheet 37b and the third sheet 37c, respectively. It is preferable that the first sheet 37a, the second sheet 37b, and the third sheet 37c are adhered to the inner surface of the case 20 via the adhesive 40.
- the raw material sheet 30 since the raw material sheet 30 has a plurality of sheets, it is possible to adopt a sheet having different raw material layers 32. Thereby, by adopting the sheet having the raw material layer 32 containing different components, various flavors can be combined and supplied to the user, and a new taste can be provided to the user.
- the first sheet 37a, the second sheet 37b, and the third sheet are simply folded along the crease F1, but the cartridge 10 is not limited to this, and at least one of these sheets is not limited to this. As shown in FIG. 13, it may be formed in a cylindrical shape.
- the raw material layer 32 extends over a part of one side of the base material layer 31 as shown in FIG. May be laminated.
- the raw material sheet 30 has been described as having the base material layer 31 and the raw material layer 32, but the raw material sheet 30 is not limited to this, and the raw material sheet 30 does not have the base material layer 31. good. That is, the first sheet 37a, the second sheet 37b, or the third sheet 37c constituting the raw material sheet 30 may be composed of only the raw material layer 32. In this case, the raw material sheet 30 may be the above-mentioned tobacco sheet or non-tobacco sheet.
- the heating blade 150a or the susceptor is inserted into the first gap 34 to heat the cartridge 10, but the present invention is not limited to this, and the heating blade 150a or the susceptor is positioned on the side surface of the raw material sheet 30.
- the raw material sheet 30 may be heated from one side. In this case, heat is gradually transferred from one side of the raw material sheet 30, and the smoking time can be lengthened.
