Title: Laminated ceramic piezoelectric body
Inventor: TOMITA MASAHIRO
IPC: H01L41/083
Filed: 1983-08-12
Abstract: PURPOSE:To prevent a crack and a breaking while keeping a function as a piezoelectric body even when such phenomena are generated by disposing blanks, which do not function as piezoelectric bodies, on both end surfaces and preventing the generation of discharge in the blank sections. CONSTITUTION:With a blank (a dummy) 11, which does not function as a piezoelectric body, an end surface on the side being in contact with a ceramic piezoelectric simple body 1 is joined by silver paste, and an electrode 2 is not formed on an end surface on the outside. When a laminated ceramic piezoelectric body is incorporated into a case, stress concentrates to a biassed section to the case of both end surfaces of the laminated ceramic piezoelectric body A and the dummies 11 on both end surfaces are often cracked 7 or broken when both end surfaces are biassed to the case and brought into contact with it. Since the electrodes are not formed on the outer end surfaces (upper end surfaces) of the dummies 11, voltage is not applied between upper and lower end surfaces, and discharge is not generated between them. Accordingly, life of the device can be lengthened.
