Document Type and Number:
Japanese Patent JP2865709
Kind Code:
B2
Abstract:
PURPOSE:To make it possible to obtain a large amount of displacement in a low voltage by a method wherein an insulating layer consisting of a polyimide resin hating a specified repeat unit is formed only on the exposed part, which is located on the side end surface of an element, of an internal electrode plate and an electrostriction material in the vicinity of the exposed part. CONSTITUTION:The end surface of an internal electrode plate is exposed on the side end surface of an element and an insulating layer consisting of a polyimide resin having a repeat unit, which is shown in a formula (I), is formed only on the exposed part, which is located on the side end surface of the element, of the internal electrode plate and an electrostriction material in the vicinity of the exposed part. In the formula (I), X is a quadrivalent group, such as a phenyl group, a biphenyl group or the like, and Y is a dihydric group, such as a phenyl group, an alkylene group or the like. Thereby, it becomes possible to lessen an interlayer distance and a laminated electrostruction effect element capable of obtaining a large amount of displacement in a low voltage can be obtained.
