り、鏡面仕上げの点で劣るという問題がある。By the way, a composition containing a polycarbonate resin as a main component and glass fiber as a filler is added to the polycarbonate to have a high rigidity. For example, a compression molding method is used. When the handle is formed, the fine needle-shaped glass fibers are projected on the surface, and as a result, fine irregularities are formed, resulting in a problem that mirror finishing is inferior.
【０００４】本発明は上記問題に鑑み、剛性（曲げ弾性
