PROBLEM TO BE SOLVED: To obtain a polycarbonate-based resin composition that has excellent thermal conductivity, molding processability, slight warpage of molding and excellent surface smoothness, its molding, especially a molding useful for OA (Office Automation), electric/electronic parts, a case body and an internal part of precision equipment part. SOLUTION: The heat-conductive polycarbonate-based resin composition comprises, based on (A) 100 parts wt. of a polycarbonate-based resin, (B)≥1 part wt. and≤40 parts wt. of an aromatic polycarbonate oligomer, (C)≥5 parts wt. and≤40 parts wt. of a graphitized carbon fiber having≥100W/m×K coefficient of thermal conductivity in the length direction and 5-20μm average fiber diameter and (D)≥5 parts wt. and≤100 parts wt. of heat-conductive powder (except boron nitride) having≥10W/m×K coefficient of thermal conductivity and 1-500μm average particle diameter. The molding is obtained by molding the heat-conductive polycarbonate-based resin composition. COPYRIGHT: (C)2007,JPO&INPIT
