A plurality of recessed portions and protruding sections are formed in an alternating manner in the vibration direction on the surfaces of each of the first surface of the movable part and the second surface of the fixed part. An electret film is formed on at least one of the fixed part and the movable part. The vibrational energy harvester device is configured so that a force factor (electromechanical conversion factor) having a value that corresponds to the gap between the first surface of the movable part and the second surface of the fixed part becomes small when the vibration amplitude of the movable part is small and large when the vibration amplitude of the movable part is large.

VIBRATING POWER GENERATION ELEMENT AND MANUFACTURING METHOD FOR VIBRATING POWER GENERATION ELEMENT
A vibrating power generation element formed by processing a substrate that has a first Si layer and a second Si layer provided via an insulating layer. The vibrating power generation element comprises: a fixed electrode formed on the first Si layer; and a movable electrode formed on the second Si layer, facing the fixed electrode via a gap formed in the insulating layer, and being movable relative to the fixed electrode.
Provided are a switching device and a switching-device adjustment method that can reduce errors in the stroke of a moving electrode. A first fixed electrode (4) travels along the z-direction in conformance with a screw member (72), so that the first fixed electrode (4) momentarily approaches and then moves away from a second fixed electrode (5), whereby the space between the fixed electrodes can be adjusted. In the adjusting, with as a reference a state in which the two fixed electrodes (4, 5) are at their closest approach with a moving electrode (3) sandwiched therebetween, the first fixed electrode (4) is moved away by a predetermined retraction amount so as to have the retraction amount be a stroke (L2) of the moving electrode. Accordingly, the amount of screw-member (72) rotation can be determined on the basis of the screw pitch and said retraction amount, and the screw-member (72) rotation amount can be managed to reduce errors in the stroke of the moving electrode (3).
