1. A molded article comprising a polyamide resin composition and an acid-modified polyolefin, wherein at least part of the polyamide resin composition and at least part of the acid-modified polyolefin are bonded to each other, and
wherein the polyamide resin composition comprises 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 amount of (A) to (E) is 100 mass %, and
wherein the amount of acid modification of the acid-modified polyolefin is 8 to 100 μmol/g.
