PROBLEM TO BE SOLVED: To provide a polyamide resin composition suitable for a blow molding, excellent in blow-molding property, especially improved with drawdown property, having less unevenness in the thickness of the hollow molded article and excellent in low temperature toughness. SOLUTION: This polyamide resin composition for blow-molding is provided by consisting of (a) 30 to 85 pts.wt. polyamide 6 resin having 3 to 6 relative viscosity measured in 98% conc. sulfuric acid solution at 25°C, (b) 5 to 50 pts.wt. polyamide 610 resin, (c) 5 to 30 pts.wt. ethylene-based ionomer resin and (d) 5 to 30 pts.wt. ethylene-based copolymeric elastomer resin (provided that the total of (a) to (d) is set as 100 pts.wt.) and having (10:1) to (1:2) range weight ratio of (a) the polyamide 6 resin to (b) the polyamide 610 resin and also 10-40 pts.wt. total of (c) the ethylene-based ionomer resin and (d) the ethylene-based copolymeric elastomer based on 100 pts.wt. total of the (a) to (d).
