Polyphenylene ether-based resin composition and molded article

A polyphenylene ether-based resin composition comprising:

• a polyphenylene ether (A);
• a styrene-based thermoplastic elastomer (B);
• a flame retardant (C);
• and
• a kaolin clay (D),
• wherein, when a total content of the (A), (B), (C), and (D) components is taken as 100 mass %, a content of the (A) component is 25 to 84 mass %, a content of the (B) component is 1 to 20 mass %, a content of the (C) component is 4 to 25 mass %, and a content of the (D) component is 11 to 30 mass %, and
• the (C) component containsan organophosphorus flame retardant (C-1) having a 10-mass % reduction temperature in a range of 380 to 430° C. as measured by the following measurement method, and an organophosphorus flame retardant (C-2) having a 10-mass % reduction temperature in a range of 330 to 360° C. as measured by the following measurement method:
• <Measurement method of the 10-mass % reduction temperature of the (C-1) and (C-2) components>
• a 10-mass % reduction temperature is determined from a heating loss curve obtained by weighing out about 10 mg of the (C-1) component or (C-2) component, which is heated from 30° C. to 800° C. at a temperature rise rate of 10° C./min under a nitrogen atmosphere in a TGA measurement apparatus,
• wherein the (C) component is a mixture of the (C-1) component and the (C-2) component, and contains 50 to 95 mass % of the (C-1) component and 50 to 5 mass % of the (C-2) component per 100 mass % of the (C) component.
