摘要: A method of making a layered electrostrictive displacement device by forming sheets of an electrostrictive material alternately with internal electrodes. The laminate formed therefrom has two opposite surfaces at which the ends of the internal electrodes are exposed and two other opposite surfaces at which alternate layers of the internal electrodes are exposed. Temporary external electrodes are formed on the latter mentioned opposite surfaces. Alternate layers of the exposed portions of the internal electrodes are plated at one surface of the laminate with a metal while using a temporary external electrode as a cathode. The exposed portions of the other internal electrodes are plated with metal using another temporary external electrode as a cathode. The non-plated portions of the plated surface are selectively removed to form recesses, and an insulating film is formed on the recesses. Portions of insulating film and the metal deposited are removed to expose the internal electrodes, and external electrodes for connection to the exposed internal electrodes are formed.
