Therefore, it was confirmed that Samples 1 to 3 provided both the feeling of reaching the end and the feeling of anticipation of reaching the end, that is, the feeling of reaching the end and the feeling of anticipation of reaching the end were compatible. This is probably because Samples 1 to 3 have less resistance when the flavor-generating article is inserted, so that a feeling of reaching the end can be easily obtained. Also, in sample 2, as shown in FIG. 15, after the resistance value rises in the local variation region, the resistance value is felt to drop, so it is considered that the feeling of reaching the end is more likely to be obtained.

  • the upper limit of the second resistance ratio is preferably 1.0 or less. If a resistance value larger than the insertion force exists in the local variation area, the user may feel uncomfortable, and the user may mistake the local variation area for the end position of the chamber. Also, the presence of excessive local resistance values may cause the flavor-generating article to buckle in the local variation region.
