Resin composition and molded body

A resin composition comprising:

• a polyamide resin (A);
• an ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B);
• and
• an ethylene-based polymer (C) that is not the ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B),
• wherein the content of the polyamide resin (A) is 50% by mass or more with respect to the total amount of the polyamide resin (A), the ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B) and the ethylene-based polymer (C),
• wherein the content of the ethylene-based copolymer (C) is less than 50% by mass with respect to the total amount of the ionomer of an ethylene-unsaturated carboxylic acid-based copolymer (B) and the ethylene-based polymer (C),
• wherein the content of the ethylene-based polymer (C) is from more than 0% by mass to 2.5% by mass with respect to the total amount of the resin composition,
• wherein the ethylene-based polymer (C) comprises an ethylene-unsaturated ester copolymer, and
• wherein the polyamide resin (A) is at least one selected from the group consisting of Nylon 4, Nylon 6, Nylon 46, Nylon 66, Nylon 610, Nylon 612, Nylon 11, Nylon 12, and a copolymer thereof.
