摘要
A piezoelectric valve whose assembly work can be efficiently performed. A piezoelectric valve according to this invention includes a valve main body having a gas pressure chamber which receives compressed gas supplied from the outside, a plate which is disposed inside the valve main body and is fixed to the valve main body, and actuators each of which has a valve element, a piezoelectric element generating, in the form of a displacement, driving force required for operation of the valve element, and a displacement magnification mechanism for magnifying a displacement of the piezoelectric element and causing the magnified displacement to act on the valve element, are fixed to each of two surfaces of the plate, and are disposed inside the valve main body together with the plate.
