<p>An optical detector comprising a semiconductor chip (1) for converting received light into an electric signal, and a resin body (2) sealing the semiconductor chip (1) and having translucency, wherein the optical detector further comprise a protector (3), which covers at least the light transmission region (11), through which light is transmitted, of the surface of the resin body on which the light falls. Covering the light transmission region (11) by the protector (3) that is less in reactivity with light than the resin body (2) suppresses deformation of the resin body (2) due to light, thus suppressing degradation of the optical characteristics of the optical detector.</p> |
