Polyamide resin composition

A molded article comprising the 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 40 to 93 mass % of an aliphatic polyamide resin (A) having an amino group concentration of 46 to 110 μmol/g, 2 to 10 mass % of an aromatic polyamide resin (B), 5 to 50 mass % of reinforcing fibers (C), and 0 to 53 mass % of a component (D) other than (A) to (C), and the total amount of (A) to (D) is 100 mass %, and
• wherein the amount of acid modification of the acid-modified polyolefin is 5 to 100 μmol/g.

A method of using a polyamide resin composition for bonding to an acid-modified polyolefin,

• wherein the polyamide resin composition comprises 40 to 93 mass % of an aliphatic polyamide resin (A) having an amino group concentration of 46 to 110 μmol/g, 2 to 10 mass % of an aromatic polyamide resin (B), 5 to 50 mass % of reinforcing fibers (C), and 0 to 53 mass % of a component (D) other than (A) to (C), and the total amount of (A) to (D) is 100 mass %, and
• wherein the amount of acid modification of the acid-modified polyolefin is 5 to 100 μmol/g.
