PROBLEM TO BE SOLVED: To obtain a polyamide multilayer injection molding usable for an automobile exterior component having an excellent balance of rigidity, impact resistance, surface impact resistance, heat resistance, surface appearance and dimensional accuracy. SOLUTION: The multilayer injection molding comprises a structure of a skin layer (A) and a core layer (B). The skin layer is made of a composition obtained by blending a polyamide (Al) of 99 to 50 wt.% with an olefin elastomer (A2) of 1 to 50 wt.%. The core layer is made of a composition obtained by blending a polyamide (B1) of 99 to 40 wt.% with a reinforcing filler (B2) of 1 to 60 wt.%.
