(57) [Problem] To provide a flame-retardant resin composition which is flame-retarded without using a halogen-based flame retardant. SOLUTION: (A) A flame retardant composed of a formaldehyde polymer (such as polyacetal and / or polydioxolane) and at least one selected from a nitrogen-containing compound (B1) and an aromatic resin (B2), and a base. The flame-retardant resin composition is composed of a resin (such as a thermoplastic resin such as a polyester resin). Examples of the (B1) nitrogen-containing compound include (a) a nitrogen-containing cyclic compound having an amino group, (b) a urea compound, and (c) a guanidine compound. Examples of the (B2) aromatic resin include a hydroxyl group and And / or a resin having an aromatic ring having an amino group in a main chain or a side chain. The proportion of the flame retardant is It is about 0.1 to 300 parts by weight based on 100 parts by weight of the base resin. |
