Abstract

A piezoelectric sounder essentially comprising a piezoelectric vibrator consisting of a metal-made vibration diaphragm pressed on a piezoelectric ceramic element, and a case housing the piezoelectric vibrator and the outer periphery of the metal-made vibration diaphragm being adhered to the inner wall of the circumferential wall of the case through an adhesive layer; which is characterized in that an annular adhesion tilt face is formed on the inner wall of the case surrounding the outer periphery of the metal-made vibration diaphragm; the adhesive layer is formed by coating the adhesion tilt face.
