ABSTRACT:
A piezoelectric electroacoustic transducer includes a piezoelectric sounding body in which bending vibration is generated by applying an alternating signal between two electrodes, a case housing the piezoelectric sounding body, and a pair of terminals insert-molded in the case. In the piezoelectric electroacoustic transducer, internal connection portions of the pair of terminals are exposed on the inside surface of the side wall portion of the case so as to extend in a direction that is substantially perpendicular relative to the piezoelectric sounding body, and the internal connection portions of the terminals are electrically connected to the electrodes of the piezoelectric sounding body by using conductive adhesive. The internal connection portions of the terminals do not largely extend inside the case and accordingly, the dimensional difference between the case and the piezoelectric sounding body is minimized.
