Title:

圧電素子、圧電アクチュエータおよび圧電トランス

Document Type and Number:

Japanese Patent JP6300255

Kind Code:

B2

Abstract:

A multilayer piezoelectric element that expands and contracts in response to an applied voltage includes external electrodes disposed on surfaces of an element body, internal electrodes connected to the external electrodes, and piezoelectric layers laminated alternately with the internal electrodes. An electrode material used for the internal electrodes or the external electrodes contains a base material composed of Ag and Pd in a weight ratio of 60/40 to 85/15 and Pt in an amount of 0.1% to 10% by weight based on the weight of the base material. Also included is a piezoelectric actuator including the piezoelectric element and a piezoelectric transformer including the piezoelectric element.
