Abstract: An inhaler has a cap body for defining a flow path and having first and second air inhalation openings for introducing outside air into the flow path from the outside; an air inhalation valve for opening and closing the first air inhalation opening by using the difference in pressure between the flow path and the outside; and a shielding section capable of selectively shielding either of the first and second air inhalation openings. The inhaler is configured to be switchable between two states that are a first state where the second air inhalation opening is shielded by the shielding section and outside air can be introduced through the first air inhalation opening by using the pressure difference and a second state where the first air inhalation opening is shielded by the shielding section and communication between the flow path and the outside through the second air inhalation opening is constantly maintained.

Abstract: A mouthpiece (160) has a concave portion (161A) provided in a wall surface defining a flow path, and the concave portion (161A) is formed to have a curved surface that is curved only in one direction when seen from the above. The concave portion (161A) is provided with slit-like communication holes (162), and a valve body (170) is fixed by a fixing member (180) to the mouthpiece (160) at a generally central portion of the concave portion (161A) in the direction in which the concave portion (161A) is curved, so as to close the communication holes (162). With this structure, even if the valve body deteriorates over time due to long-term use, or the valve body deforms due to long-term use or cleaning and disinfection, its function as an exhalation valve is less likely to be impaired, and as a result, an inhaler capable of preventing leakage of aerosol can be provided.
