摘要：
There is provided a piezoelectric valve including: a valve main part including a gas pressure chamber that receives compressed gas supplied from an outside; a plate disposed inside the valve main part, and an actuator fixed to the plate and disposed inside the valve main part together with the plate. The valve main part is a case with an opening on a front surface. The plate is provided with a gas discharge path and a valve seat with which a valve element of the actuator comes into contact. The actuator opens and closes the gas discharge path. A lid member that closes the opening of the case has a gas discharge opening that communicates with the gas discharge path of the plate; is welded and fixed to a front surface of the plate, where the gas discharge path opens, on an annular welded part surrounding the gas discharge opening; and is welded and fixed to an end surface of the case on an annular welded part on the outer peripheral part.
