Provided is a polyphenylene ether flame-retardant resin composition having excellent flame retardance and long-term flame retardance. The flame-retardant resin composition contains: (A) a resin including (A-1) a polyphenylene ether; and (B) a flame retardant. The (A-1) component has a content of 50 mass% or more when the flame-retardant resin composition minus ash content, corresponding to a residue obtained upon burning of the flame-retardant resin composition, is taken to be 100 mass%. A shaped article of 12.6 cm in length, 1.3 cm in width, and 1.6 mm in thickness formed from the flame-retardant resin composition exhibits a rate of change of chloroform-insoluble content of 15 mass% or less through aging in which the shaped article is left for 1,000 hours at 150°C in an atmospheric air.
