Abstract
Abstract A reflecting plate comprising a substrate, a synthetic resin interlayer formed on the surface of the substrate, and a thin metallic film formed on the synthetic resin interlayer. The reflecting plate may further comprise a transparent synthetic resin layer on the surface of the thin metallic film. A typical use of the reflecting plate is with an illuminating lamp is an electrostatic copying apparatus.
