Abstract

A fluid control device includes a piezoelectric pump, an inhaler, and a valve. The piezoelectric pump has a gas suction hole and a gas discharge hole. The inhaler has a container, an inhalation port, and a connection hole. The valve has a first ventilation hole, a second ventilation hole, a third ventilation hole, a first valve housing, a second valve housing, and a valve body. The first ventilation hole of the valve is connected to the connection hole of the inhaler. The second ventilation hole of the valve is connected to the suction hole of the piezoelectric pump. The third ventilation hole of the valve is opened to the atmosphere. The valve body is held between the first valve housing and the second valve housing, and configures a first region and a second region.
