Abstract
A light reflecting plate includes a thermoplastic polyester foam containing fine cells with a mean cell diameter of 50 .mu.m or less and having a thickness of 200 .mu.m or more and a specific gravity of 0.7 or less. This light reflecting plate exhibits a high diffuse reflectance of visible light without adding a pigment or fine particles for improving the light scattering properties.
