<P>PROBLEM TO BE SOLVED: To provide a non-halogen-based flame-retardant resin composition completely free from antimony, phosphorus and phosphorus compounds and giving molded products excellent in surface appearance and mechanical characteristics. Ž<P>SOLUTION: The flame-retardant resin composition comprises (a) a thermoplastic resin or a thermosetting resin, (b) polyimide particles and (c) a metal hydrate, as essential components, wherein the polyimide particles to be used is obtained by wet-grinding polyimide films or sheets as raw materials by a millstone type grinder to the extent that parallel planes derived from the polyimide film or sheet disappear.
