Abstract
A flame retardant resin composition possessing high anti-thermal characteristic, excellent anti-impact characteristic and moreover, high degree of flame retardation characteristic, comprising: a polycarbonate resin (A-1), optionally a thermoplastic resin (A-2) other than polycarbonate group resin, a phosphoric ester (B); and an alkoxy group-containing organopolysiloxane (C) expressed by the average compositional formula R1aSi(OR2)bO(4-a-b)/2, where R1 is a substituted or unsubstituted univalent hydrocarbon group containing an aryl group as an essential component; R2 is a substituted or unsubstituted univalent hydrocarbon group; R1 and R2 may be the same as or different from each other; 0.2≦a≦2.7; 0.2≦b≦2.4; and a+b<3.
