PURPOSE:To increase the amount of displacement by a method wherein a part including the outer periphery of internal electrodes is removed, and an external electrode whereto the internal electrode is connected is formed thereat, in a lamination type electrostrictive effect element. CONSTITUTION:The internal electrode 22 of the elecrrostrictive effect element has a form with the removal of a part including the outer periphery. The removed parts are laminated so as to superpose at intervals of a layer, and thus sintered. Next, Ag paste is coated on the side surface of the laminated electrostrictive effect element, and then the external electrodes 33 are formed by baking. These electrodes 33 connect each internal electrode 32 at intervals of a layer. The amount of displacement increases, since the superposition areas between each internal electrode increase. |
