[0167] Using the compounding amounts shown in Table 1, using components (A) to (E), using a twin-screw extruder with a vent (manufactured by Toshiba Machine Co., Ltd., "TEM-37SS", L / D=40.5) Pellets were obtained by melt-kneading at a cylinder temperature of 320°C. When melting and kneading with a twin-screw extruder with a vent, add ion-exchanged water (conductivity: 1 μS / m or less), the degree of vacuum at the outlet of the exhaust port was reduced to -720 mmHg, and melt kneading was performed to obtain pellets. Table 1 shows the evaluation results of the pellets formed from the obtained polycarbonate resin composition and the evaluation results of the test pieces injection-molded using the pellets. In addition, the silicone compound of the (B) component used in the Example and the comparative example used the silicone compound "trade name: KR-511" manufactured by Shin-Etsu Chemical Co., Ltd. of the same grade, although the same Five batches of silicone compounds "KR-511(a...
