(57) [Abstract] [Purpose] To provide a thermoplastic resin composition having excellent water resistance, flame retardancy, fluidity, heat resistance and impact resistance. A resin composition comprising (A) a thermoplastic resin, (B) an organic phosphorus compound, or a phosphorus-containing flame retardant obtained by mixing an organic phosphorus compound and red phosphorus, the resin composition comprising: The degree of hydrolysis of the organic phosphorus compound in the phosphorus-containing flame retardant is 1500 as the value of the total acid amount specified in MIL-H19475. A good-flowing flame-retardant heat- and impact-resistant resin composition having excellent water resistance, which has a value of KOH ยท mg or less. |
