The present invention is a reinforced thermoplastic resin composition containing a main resin component (C) obtained from a polycarbonate resin (A) and a graft copolymer (B) as a discretionary component, an inorganic filler (D), a glycidyl ether unit-containing polymer (E) (excluding (B)) of 3,800 - 60,000 Mw, and a phosphorus-containing modified polyester resin (H) in which a phosphorus-containing polyester resin (F) has been modified with a polycarbodiimide compound (G). In the reinforced thermoplastic resin composition: (B) is a polymer obtained by polymerizing a monomer mixture comprising an aromatic alkenyl compound monomer (a) and a vinyl cyanide compound monomer (b) in the presence of a rubber polymer (B1); in (C), the contents of (A) and (B) are 80-100 mass% and 0-20 mass% respectively, and the total content of (A) and (B) is 100 mass%; (F) comprises the cyclic phosphorus compound-containing dicarboxylic acid component of formula (1); the phosphorus content is at least 4 mass%; the proportion of (D) is 20-50 mass% with respect to the reinforced thermoplastic resin composition; the content of (E) is 1-10 parts by mass with respect to 100 parts by mass of (C); and the content of (H) is 3-10 parts by mass with respect to 100 parts by mass of (C). |
