PURPOSE:To remove a lead wire for applying applied voltage, and to eliminate the lowering of reliability on a connection due to breaking, etc. of the lead wire completely by forming an electrode plate to a mounting surface for an element and applying applied voltage to an internal electrode plate through the electrode plate through the electrode plate. CONSTITUTION:Internal electrode plates 32 are formed on the surfaces of electrostriction material films 31 mainly comprising magnesium lead niobate through the screen printing of platinum paste, and a fixed number of the film 31 are laminated, hot-pressed and sintered. Insulators 33, 33' are applied on the end surfaces of the internal electrode plates 32 on every other layer, first and second conductive substance layers 34, 34' are formed, and electrode plates 35, 35' are shaped on the upper and lower surfaces of a laminate. When mounting members 50, 51 are set up on the upper and lower surfaces (mounting surfaces) of an electrostriction effect element and voltage is applied between the mounting members 50, 51, voltage can be applied to the internal electrode plates 32 through the conductive substance layers 34, 34' and the electrode plates 35, 35'. |
