Abstract
A hermetically sealed electrostrictive actuator comprises a metal case and a metal cap for housing an electrostrictive element therein. The metal cap is provided with a pair of glass sealing terminals to be connected to a pair of lead wires of the electrostrictive element. The metal case is provided a flexible region so as to follow the expansion and constraction of the electrostrictive element without breaking the hermetic envelope of the metal case and the metal cap.
