• Seventh Embodiment Figure 16 is a diagram showing a longitudinal section of the flavor inhalation article 7 relating to the seventh embodiment, in which (A) shows a state in which the limiting member 33 is positioned on the first side of the aerosol modifier 34, (B) shows a state in which the limiting member 33 is positioned on the second side of the aerosol modifier 34, and (C) shows a state in which the limiting member 33 is positioned on both the first and second sides of the aerosol modifier 34.
• the flavor inhalation article 7 according to the seventh embodiment is different from the flavor inhalation article 5 according to the fifth embodiment in that the filter section 730 corresponds to the filter section 30.
• the filter section 730 according to the seventh embodiment is different from the filter section 30 according to the fifth embodiment in that the filter section 730 has a plurality of restricting members having different shapes.
• the same reference numerals are used for the same parts in the fifth and seventh embodiments, and detailed descriptions thereof will be omitted.
• the filter unit 730 has a filter 31 which is a paper filter, a restricting member 33 which restricts the flow path of the aerosol, 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 730 is connected (coupled) to the base material unit 10 by winding the base material unit 10 and the filter unit 730 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 730 can be, for example, the same as the aerosol modifier 34 included in the filter section 3330 according to the third embodiment.
• a communication hole 560 may be provided in the region between the restricting members 33 and the aerosol modifier 34, as shown in Figure 16 (C).
