ことを特徴とする圧電形変換器。 In a piezoelectric bimorph diaphragm constructed by attaching a circular piezoelectric plate to one central part of a conductive oscillating substrate, the outer periphery 12 of the oscillating substrate has a cutout that protrudes beyond the outer periphery of the cover of the oscillating substrate. A protruding piece is installed, and this is configured to double as one terminal plate, and a groove and a terminal plate are provided on the side of the frame into which the vibrating board cut out piece is inserted, and the center of the vibrating board cut out piece is provided. The diaphragm and frame are caulked together using a cover that matches the center position of the terminal plate, and that the width of the cut-out piece is larger than the width of the terminal plate, and that has a notch on the side surface. A piezoelectric transducer characterized by comprising:
