PROBLEM TO BE SOLVED: To obtain a flame-retardant resin composition that has all of high flame retardance, heat stability, light resistance and fluidity, is readily melted and kneaded by an ordinary compound apparatus and has excellent surface impact strength and Charpy impact strength. SOLUTION: The flame-retardant resin composition is obtained by mixing 100 parts wt. of a thermoplastic resin with 5-50 parts wt. of a flame retardant that is represented by general formula (I) (X is bromine or chlorine; R<SP>1</SP>and R<SP>2</SP>are each a glycidyl group or its alcohol addition group), has 700-1,500g/eq epoxy equivalent, 100-150°C softening point, a molecular weight distribution of≤20 wt.% of a component having 2,000-10,000 molecular weight, 10-75 wt.% of a component having <2,000 molecular weight and≥5 wt.% of a component having >10,000 molecular weight and 500-1,300 number-average molecular weight and 1-20 parts wt. of a flame-retardant auxiliary.
