Patent ID: 8062460

Claim:
A laminated piezoelectric ceramic element manufacturing method, comprising: providing a first laminated body which includes a plurality of piezoelectric body layers of piezoelectric ceramic, and stripe shape internal electrodes disposed on at least one interface between adjacent piezoelectric body layers in the first laminated body; cutting the first laminated body in a laminating direction so as to have a width-direction dimension corresponding to a width dimension of a laminated piezoelectric body to be ultimately obtained, to obtain a plurality of second laminated bodies having the width-direction dimension; laminating two or more second laminated bodies in the laminating direction of the piezoelectric body layers, to obtain a third laminated body; providing a joint material so as to join adjacent second laminated bodies in the third laminated body in order to temporarily bond the laminated second laminated bodies to one another; cutting the third laminated body in the laminating direction and in a direction parallel to the width direction of the second laminated body, to obtain a laminated piezoelectric body; and baking the laminated piezoelectric body.
