PROBLEM TO BE SOLVED: To obtain the above composition, having excellent mechanical characteristics and heat resistance, excellent in friction and abrasion resistances and useful for sliding members, etc., by blending nylon 46 resin with potassium titanate whiskers and an ultrahigh-molecular weight polyethylene resin powder. SOLUTION: This polyamide resin composition is obtained by blending (A) 60-90wt.% nylon 46 resin and (B) 10-40wt.% potassium titanate whiskers with (C) an ultrahigh-molecular weight polyethylene resin powder with the proviso that the intrinsic viscosity [η] measured in a decalin solvent at 135 deg.C is >=10dl/g; the total amount substantially passes through a 100-mesh screen; at least >=20wt.% passes through a 350-mesh screen and the average particle diameter is <=80μm} in an amount of 0.1-5 pts. by wt. based on 100 pts. by wt. total amount of the components (A) and (B).
