The incident side electrode layer is provided with plural openings bored through the layer, and has a thickness of 10 nm to 200 nm. Each of the openings occupies an area of 80 nm2 to 0.8 μm2, and the opening ratio is in the range of 10% to 66%. The transmittance of the whole cell is 5% or more at 700 nm wavelength. The incident side electrode layer can be formed by etching fabrication with a stamper. In the etching fabrication, a mono-particle layer of fine particles or a dot pattern formed by self-assembled block copolymer can be used as a mask.

A driving element is formed on a central portion of the beam-like vibrating body, and feedback elements are formed on both ends. A physical quantity acting on the beam-like vibrating body is detected by causing natural vibration in the beam-like vibrating body and detecting a natural frequency of the vibrating body. This enables reliable detection of a physical quantity, such as a strain or load, acting on an object.
