Abstract

The present invention relates to a polyamide resin composition that is excellent in mechanical characteristics, bonding properties and calcium chloride resistance and is suitably bonded to an acid-modified polyolefin, wherein the polyamide resin composition includes 70 to 99 mass % of an aliphatic polyamide resin (A) having an amino group concentration of 46 to 110 μmol/g, 0 to 18 mass % of an aromatic polyamide resin (B), 0.01 to 0.50 mass % of a polyalkylene glycol alkyl ether (C), 0.01 to 0.50 mass % of a polyolefin wax (D) and 0 to 22.98 mass % of a component (E) other than (A) to (D), and the total of (A) to (E) is 100 mass %, and wherein the acid-modified polyolefin having an amount of acid modification of 8 to 100 μmol/g.
