Claim Text:
1. A polycarbonate resin composition comprising polycarbonate resin (A) and a total of 5 to 30 parts by mass of an oligomeric phosphoric acid ester flame retardant (B1) and a phosphazene flame retardant (B2), 3 to 9.7 parts by mass of a siloxane-based core/shell elastomer (C) and 0.8 to 5 parts by mass of carbon black (D) with respect to 100 parts by mass of polycarbonate resin (A), wherein a content ratio of the oligomeric phosphoric acid ester flame retardant (B1) to the phosphazene flame retardant (B2) is 1 to 49 mass % of (B1):99 to 51 mass % of (B2), the siloxane-based core/shell elastomer (C) has a silicon content of 9.1 to 30 mass % and a number-average particle size in the range of 50 to 1,000 nm, and a flow rate per unit time of the resin composition is 15 to 50×10
