• FIG. 14 is a diagram showing a longitudinal section of the flavor inhalation article 5 according to the fifth embodiment, in which (A) shows a state in which the low filtration member 33 is positioned on a first side within the filter 31, and (B) shows a state in which the low filtration member 33 is positioned on a second side within the filter 31.
• the filter section 530 has a filter 31 connected to the second side of the base member 10 and another filter 32 located on the second side of the filter 31.
• the filter 31 is located on the upstream side, and the other filter 32 is located on the downstream side.
• the filter unit 630 has a filter 31 which is a paper filter, a low filtration member 33 having a filtration rate lower than that of the filter 31, an aerosol modifier 34 which modifies the aerosol, and a winding paper 35 which is present between the filter 31 and the tipping paper 40 and which is wound around the outer circumferential surface of the filter 31.
• the filter unit 330 is connected (coupled) to the base material unit 10 by winding up the base material unit 10 and the filter unit 630 together using the tipping paper 40.
• the winding paper 35 may not be provided.
• the configuration of the aerosol modifier 34 in the filter section 630 can be, for example, the same as the aerosol modifier 34 included in the filter section 330 according to the third embodiment.
• a communication hole 460 may be provided in the region between the low filtration member 33 and the aerosol modifier 34.
• the communication hole 460 may be provided in the downstream region of the aerosol modifier 34.
• 15B in the case where the aerosol modifier 34 is disposed on the first side (upstream side) of the low filtration member 33 and in a straight line with the low filtration member 33 in the center line direction, the communication hole 460 may be provided in the region between the low filtration member 33 and the aerosol modifier 34.
• An article for inhaling flavor comprising: a base portion including an aerosol source; and a filter portion through which the aerosol generated from the base portion passes, the filter portion having a paper filter filled with a sheet member so that voids are formed along the longitudinal direction of the filter portion; and a low filtration member disposed on the paper filter and having a filtration rate lower than that of the paper filter.
• the flavor inhalation article according to (1) wherein the paper filter is a filter in which the sheet member is gathered.
• the flavor inhalation article according to (2), wherein the filling density of the sheet member is 90 mg/ cm3 or more and 720 g/ cm3 or less.
