A halogen-free flame-retardant polyamide composition which generates no halogen compound during combustion. The composition has excellent thermal stability during high-temperature molding and is capable of showing high flame retardancy when burned. The composition is effective in inhibiting steel materials ; such as the screw or cylinder of an extruder or molding machine, from corroding or wearing. The flame-retardant polyamide composition in a preferred embodiment comprises 20-60 mass% polyamide resin (A), 5-40 mass% thermoplastic resin (B) other than (A), 3-15 mass% flame retardant (C) having no halogen radicals in the molecule, and 0-50 mass% reinforcement (D), wherein the thermoplastic resin (B) satisfies the UL94V-© standards, the flame retardant (C) is a phosphinic acid salt compound, and the sum of the thermoplastic resin (B) and the flame retardant (C) is 16-45 mass%. |
