PURPOSE:To reduce the size and voltage for an electrostrictive effect element used as an actuator, to reduce a manufacturing cost and to improve reliability. CONSTITUTION:An inner electrode 2 is screen printed on one side surface of an electrostrictive ceramic green sheet 7. The two sheets are superposed, wound, and baked. In this case, the respective sheets are so superposed that the surfaces printed with the electrodes 2 are directed in the same direction. Thereafter, a lead is soldered to the exposed part of the electrode. An electrostrictive element which can be driven by a low voltage, is reduced in size and enhanced in reliability, can be obtained. Manufacture of the element is very facilitated, and a manufacturing cost can be remarkably reduced. Further, since the element according to this invention is expandable radially to the central axis of winding, it can be used for new utility which is not heretofore employed. |
