<p>In the present invention, a piezoelectric converter is provided with a supporting section, a facing section, and an oscillation block. The oscillation block is present between the supporting section and the facing section, and has one edge fixed to the supporting section and the other edge set apart from the facing section. The oscillation block is provided with a beam section, a weight section, a protrusion section, and a piezoelectric conversion section. The beam section is thinner than the supporting section, and is swingably supported by the supporting section. The weight section is provided at the front edge of the beam section, and is thicker than the beam section. The protrusion section protrudes toward the opposite side of the weight section to the beam section side, and is thinner than the weight section and the facing section. The piezoelectric conversion section generates an AC voltage in accordance with the oscillation of the beam section. The oscillation block is bent so as to prevent a normal to the front edge surface of the protrusion section from intersecting the facing section.</p> |
