Abstract:
1. A motion sensor comprising: a lower substrate having a first electrode section; an upper substrate having a second electrode section; between the lower and upper substrates, a vibrator movably supported by an elastic beam section, the vibrator having a three-layered structure composed of a first conductive layer, an insulating layer and a second conductive layer; between the lower and upper substrates, a support section formed of the first conductive layer, the insulating layer, and the second conductive layer, and supporting the beam section; and between the lower and upper substrates, a conducting section separate from the vibrator and formed of the first conductive layer, the insulating layer, and the second conductive layer, the conducting section being electrically isolated from the support section, and connecting the first electrode section to the upper substrate, wherein,
