Abstract
An electrostriction effect element having a simplified construction through the provision of a relatively thick connection portion disposed between two actuator portions. The connection portion preferably has a thickness greater than that of the solder or lead wires which are provided to connect the overall element. As a result, soldering is considerably simplified. Additionally, protection portions may be added at opposite ends of the pillar of electrostrictive material, sandwiching the actuator portions and the connection portion. The protection portions also preferably have a thickness greater than that of any of the electrostrictive layers in the pillar. Still further, buffer layers may be provided between the connection portion and each of the actuator portions, and also between the actuator portions and the protection portions. These buffer layers also preferably have a thickness greater than that of any of the electrostrictive layers in the pillar material. The overall element may be rectangular or cylindrical in cross-section.
