子に接続したことを特徴とするピエゾポンプ。 A pair of diaphragms are stretched around an annular frame at intervals, and a pump chamber is formed between the two diaphragms and communicates with the outside through an inlet and an outlet provided in the frame. A piezoelectric ceramic plate having electrode layers formed on both the front and back sides is adhered to the outer surface of the diaphragm, and the electrode layers of both piezoelectric ceramic plates are connected to a pair of electrode terminals fixed to the frame. The electrode terminals are connected to an alternating current power source, and the piezoelectric ceramic plates are made to alternately expand and contract, and the two diaphragms are deflected alternately in a direction in which the corresponding surfaces move away from each other and in a direction in which the corresponding surfaces approach each other. In the piezo pump, the fluid sucked into the pump chamber from the suction port is discharged from the discharge port by alternately increasing and decreasing the volume. A conductive layer that is electrically connected to the electrode layer on the back side is formed in the deleted part, and the conductive layer and the electrode layer on the front side are connected to the pair of electrode terminals with lead wires. A piezo pump characterized by being connected.
