And a filter element (1) that the spectral transmission light, and a photodetector (2) having a plurality of light receiving elements. The filter member 1 and a plurality of projections formed of a first metallic material on one surface of the substrate, a substrate having a light transmitting property, a first metal material than the refractive index is high the second by a metallic material, a plurality of convex portions and together and a metal film is formed to cover one surface of the substrate. A plurality of metal present between the convex part of the convex portions adjacent film is a diffraction grating, is disposed such that the convex portion waveguide. The grating period of the diffraction grating, and at least one of the convex portions and the height of the metal film thickness, and to change the wavelength of light transmitted through each portion of the filter member, and each portion is set to a different value. The photodetector (2) are arranged in each of the plurality of light-receiving element 21, so as to receive the light transmitted through the filter element (1).
