Abstract

PURPOSE:To facilitate the connection of power supply lines by creeping the electrodes formed on both main surfaces of a piezoelectric ceramic element body to the sides of the body and to the other main sides of the body. CONSTITUTION:In the first piezoelectric ceramic element 10, an electrode 13 is crept not only to the lower surface of the piezoelectric ceramic body 11 but also to the upper surface of the body 11 via a part of the longitudinal sides of the body 11. An electrode 12 is crept through the part except the creeping part 13a of the longitudinal side of the body 11 to the lower surface of the body 11. A slit for isolating the creeping parts 12a, 13a is formed between the parts 12a and 13a. In the second piezoelectric ceramic element 20, the creeping part 23a of the electrode 23 is formed on the side and upper surfaces of the piezoelectric ceramic element body 21 similarly, and the creeping part 22a of the electrode 22 is formed on the side and upper surfaces of the body 21. The creeping parts 12a, 22a and 13a, 23a are connected with conductor adhesives 40.
