PURPOSE:To uniformize electric signals obtained from a plurality of optical receptors by forming the thickness and the shape for reducing the influence of an incident light incident on a photodetector by reflecting the light to the thickness between the light transmission surface of a sealer profile and the light transmission surface. CONSTITUTION:A photoelectric converter 1 is fixedly held to a photoelectric converter supporting member 2, wire bonded by extrafine metal wirings 3 to a lead terminal 2', then integrally molded by molding means, such as transfer molding with light transmission resin 4, and a profile is formed. A mold uses a mold having a large distance D between the light transmission surface of a sealer profile and the converter 1. When a light beam 6 is emitted perpendicu larly to the profile of the resin 4 and the converter 1, the larger the distance D is, the narrower the region where the reflected light is incident to a photode tector 5 to reduce the influence by the reflection. Since the optical path is lengthened, the absolute value of the intensity of the incident light is reduced to reduce the influence thereto. |
