摘要： A piezoelectric pump is capable of reliably discharging gas and reliably transporting liquid even when intermittently driven. The piezoelectric pump includes a piezoelectric vibrator, a diaphragm deflected and deformed by the piezoelectric vibrator, a pump chamber including at least one wall surface defined by the diaphragm, an inlet through which liquid, gas, or a mixture of liquid and gas flows into the pump chamber, an outlet through which the fluid is discharged, and a liquid holding member arranged to provide a gap between the liquid holding member and the inner surface of the pump chamber and to maintain the liquid in the gap using capillary effect or surface tension. A flow passage plate includes a flow passage groove provided therein.

摘要： A check valve is housed in a valve chamber and includes a support portion and a flexible portion. The support portion extends along a principal axis thereof. The flexible portion is supported by the support portion in a manner extending from the principal axis. A diaphragm defines a lower wall of the valve chamber, and includes an inflow port for fluid at a position that is closed with the flexible portion when the flexible portion is displaced. A bottom plate defines an upper wall of the valve chamber, and faces the diaphragm with the flexible portion arranged therebetween. An uneven portion is provided in at least one of mutually facing areas of an upper principal surface, which is one of two principal surfaces of the flexible portion and faces the bottom plate, and a lower principal surface of the bottom plate, the uneven portion being partially uneven.
