  • the flavor inhaler 100 can improve the degree of freedom of control of the amount of aerosol and the amount of flavor to be inhaled by a user, by having the flow rate adjustment mechanism 112 explained above. For example, by changing a cross-sectional area of a flow path of one or both of the first flow path 110 A and the second flow path 110 B, the air flow rate ratio ⁇ (and the aerosol flow rate ratio ⁇ ) is changed, and, in response thereto, change in the amount of aerosol flowing through the first flow path 110 A and the amount of aerosol flowing through the second flow path 110 B occur. Further, change in the amount of aerosol flowing through the first flow path 110 A leads to change in the amount of the flavor component supplied to a user. Thus, the user can freely adjust the ratio between the aerosol and the flavor component which are to be inhaled.
