A thermoplastic resin composition including a matrix phase and a dispersion phase, the thermoplastic resin composition characterized in that the matrix phase includes (A1) at least one type of polyamide resin having a melting point of 170-210°C, (A2) at least one type of polyamide resin having a melting point of 210-265°C, and (B) at least one type of ethylene-vinyl alcohol copolymer, the dispersion phase includes (C) at least one type of acid-modified elastomer, the amount of the acid-modified elastomer (C) is 100-240 parts by mass with respect to a total of 100 parts by mass of the polyamide resins (A1) and (A2) and the ethylene-vinyl alcohol copolymer (B), the amount of the polyamide resin (A2) is 20-40 mass% based on the total mass of the polyamide resin (A1), the polyamide resin (A2), and the ethylene-vinyl alcohol copolymer (B), and the total amount of the polyamide resin (A1) and the polyamide resin (A2) is 35-70 mass% based on the total mass of the polyamide resin (A1), the polyamide resin (A2), and the ethylene-vinyl alcohol copolymer (B). |
