Abstract

Plural conductive plates extend from a transparent containing unit containing the photoelectric conversion device, plural electrical circuit components are connected to the conductive plate, and the conductive plate extending from the transparent containing unit is accommodated in a housing while the conductive plate is bent. At that time, the conductive plate extending from the transparent containing unit is coupled at two portions in an extending direction by coupled-fixing members made of non-conductive synthetic resin, the electrical circuit components are mounted between the coupled-fixing members and the conductive plate is bent at portions outside these two coupled-fixing members. In the case that the conductive plate must be cut to generate a floating point portion, a floating-point fixing member is provided for coupling and fixing the floating point portion to an adjacent conductive plate.
