クチユエータ。 In a laminated piezoelectric actuator having a structure in which an actuator element is cased by a case, a pedestal, and a lid, the case housing the actuator element has slits provided at two locations at the lower end of the side surface, which serve as external connection terminals for the actuator element. The outside of the part of the lead wire that comes into contact with the slit is covered with a heat shrink tube and is heat shrinked,
The lead wire covered with the heat shrink tube is pulled out from the slit, the actuator element is fitted into the case, and the lead wire covered with the heat shrink tube is held between the upper end of the slit of the case and the base fixed to the lower part of the actuator element. This is a multilayer piezoelectric actuator characterized by a structure in which the lead wire extraction part is hermetically sealed and the pedestal and lid are fixedly sealed to the case.
