PROBLEM TO BE SOLVED: To prepare a flame retardant resin composition having high flame retardancy, mechanical characteristics, heat resistance, bleed resistance in wet heat treatment and contamination resistance of contact points in moisture heat treatment, and scarcely causing deterioration in electric characteristics in wet heat treatment. SOLUTION: This flame resistant resin composition is prepared by including (A) 100 pts.wt. thermoplastic polyester resin, (B) 5-100 pts.wt. resin showing <=70% weight loss at 600 deg.C according to a thermal test in air at 40 deg.C/min heating speed and (C) 0.1-30 pts.wt. red phosphorus having 0.1-1,000μS/cm electric conductivity. The electric conductivity is measured by adding 100 mL purified water to 5 g red phosphorus, by the extraction treatment at 121 deg.C for 100 h., by filtering the red phosphorus and by diluting the filtrate with purified water so as for the total volume to become 250 mL. |
