In this case, the susceptor-containing sheet 20 has a shorter length than the entire length of the flavor-generating article 10 in the longitudinal direction d1. Alternatively, the susceptor-containing sheet 20 has a length of less than one circumference. Therefore, the flavor-generating article 10 does not need to be provided with a susceptor-containing sheet 20 having the same size as the entire size of the flavor-generating article 10, so a necessary amount of susceptor-containing sheet 20 is provided for the flavor-generating article 10, and the susceptor material is can be reduced.

If the thickness of the tobacco sheet 21 is less than 0.25 mm, the amount of flavor or aerosol generated per unit area of the sheet may decrease. If the thickness of the tobacco sheet 21 exceeds 4.0 mm, the size of the flavor-generating article 10 will become too large. In this case, since it takes time to heat the tobacco sheet 21, there is a risk that it will take time to complete the initial puff or that the amount of initial puff delivered will be insufficient. Therefore, if the thickness of the tobacco sheet 21 is within the above range, flavor or aerosol can be sufficiently generated and the size of the flavor-generating article 10 can be suppressed.
