Abstract: PURPOSE:To improve the efficiency of light input to a light guide part facing an electrode and the efficiency of light output from this light guide part by sectioning the end part of an optical layer on the opposite side from a buffer layer in a tapered shape. CONSTITUTION:The optical layer 8 formed of the same material with the buffer layer 12 is fitted successively to the front end surface 12f and rear end surface 12r of the buffer layer 12, so waveguide light 20 is prevented by those buffer layer end surfaces 12f and 12r. Then the end part of the optical layer 8 on the opposite side from the buffer layer 12 gradually decrease in thickness toward the end edges and has a tapered sectional shape where the layer surface smoothly connects with the substrate surface (directly to the surface of a light guide 11), so the waveguide light 20 is never reflected by the end surface of this optical layer 8. Consequently, the efficiency of light input and output at the light guide part facing the EOG electrode 13 can be made sufficiently high.
