Zusammenfassung:PURPOSE:To provide the titled composition having excellent heat resistance and mechanical properties, low molding shrinkage and high releasability, by compounding a specific amount of a fibrous reinforcing material or an inorganic filler together with a specific amount of a fluororesin to a base resin. CONSTITUTION:(A) 20-80(wt)% polycarbonate derived from a dihydric phenol of formula (X is 1-10C alkylene, -O-, etc.; R and R are halogen or 1-12C alkyl; m and n are 0-4; p is 0 or 1) (preferably bisphenol A) and a carbonic acid derivative (e.g. phosgene) with (B) 10-70% fibrous reinfocing material (e.g. glass fiber) or an inorganic filler (e.g. talc) and (C) 0.5-20% fluororesin (e.g. tetrafluoroethylene resin).
