PURPOSE: To obtain a polyamide resin composition excellent in mold processability and shaft penetration and causing little mold wear. CONSTITUTION: This high specific gravity polyamide resin composition is obtained by blending (a) 100 pts.wt. polyamide resin with (b) 200-900 pts.wt. composition prepared by blending 100 pts.wt. atomized iron powder having >=95% purity with 50-200 pts.wt. zinc oxide obtained by a wet method and having 1-15μm average particle size.
