    摘要： Provided is a relatively easy-to-fabricate piezoelectric power generating element capable of generating a large amount of electric power while comprising a bridge-type vibration beam that is resistant to damage from external vibration. This element comprises a support member, a strip-shaped vibration beam, a piezoelectric layer, and electrodes. The first and second ends of the vibration beam are fixed to the support member. The piezoelectric layer and the electrodes are provided on the surface of the vibration beam. The vibration beam extends in a plane when it is not vibrating. The vibration beam has a first portion that extends from the first end fixed to the support member, a second portion that extends from the second end fixed to the support member, and a third portion that connects the end of the first portion opposite to the first end and the end of the second portion opposite to the second end. The vibration beam has a shape such that, when viewed in a direction perpendicular to the plane, a first direction in which the first portion extends is a direction closer to the second end, and a second direction in which the second portion extends is a direction closer to the first end, the first and second directions each make an angle of more than 0° and less than 90° with respect to a straight line connecting the center of the first end and the center of the second end, and the third portion intersects once the straight line.
