Abstract
The present invention provides a resin molded body for optical parts, and comprises a solid solution of a polycarbonate and a polyester carbonate. In the resin molded body of the present invention, when the amount incorporated of the polyester carbonate is increased, the light transmission loss is increased, but the distortion temperature is considerably raised and a high heat resistance is obtained.
