Abstract

A reinforcing plate is placed on the entire surface of a piezoelectric ceramic element which oscillates upon application of a voltage, and then the piezoelectric ceramic element and the reinforcing plate are locally bonded at one or more positions. A stator is bonded to a part of the reinforcing plate corresponding to the bonded portion, and oscillation of the piezoelectric ceramic element is transmitted to the outside. Consequently, a structural defect such as cracking or chipping does not take place in the piezoelectric ceramic element even if it is subjected to falling impact, and a significant oscillation of the piezoelectric ceramic element can be ensured.
