A flame retardant resin composition comprising 100 parts by weight of the following component (A) or (B) and 0.01 to 30 parts by weight of red phosphorus (C) shows excellent flame retardancy even if the molding obtained from it is thin, and is excellent in mechanical properties, wet heat resistance and electric properties, being suitable for mechanical parts, electric and electronic parts, automobile parts, and housings and other parts of office automation apparatuses and household electric appliances. (A) (a1) 67 to 99.99 wt% (based on the total weight of (a1) and (a2)) of a thermoplastic resin other than polyethylene terephthalate and ethylene terephthalate copolymers and (a2) 33 to 0.01 wt% (based on the total weight of (a1) and (a2)) of polyethylene terephthalate and/or an ethylene terephthalate copolymer (B) a thermoplastic resin consisting of the following structural components (I), (II), (III) and (IV): <IMG> (I) <IMG> (II) <IMG> (III) <IMG> (IV) (where R1, R2 and R3 stand for, respectively independently, a divalent aromatic residue.)
