Abstract
Provided is a flame retardant resin composition excellent in flame retardance, and surface smoothness, appearance, flame retardance and electrical properties after a long-term thermal aging (e.g. 150° C., 500 hours) while maintaining mechanical and electrical properties. The disclosed flame retardant resin composition is a flame retardant resin composition containing a polyphenylene ether, in which, based on UL94 flammability test, an average burning time of a molded product having a length of 12.6 cm, a width of 1.3 cm and a thickness of 1.6 mm formed of the flame retardant resin composition before and after the aging processing in which the molded product is left to stand at 150° C. for 1000 hours under the atmospheric pressure is within 10 seconds, and a change rate of chloroform-insoluble component of the molded product before and after the aging processing is 15 mass % or less.
