Provided is a thermoplastic resin molded article that achieves both oxygen barrier properties and water vapor barrier properties and has sufficient heat-sealing properties. A thermoplastic resin molded article having at least a central layer 10 containing a polyolefin-based thermoplastic resin and an ethylene-vinyl alcohol copolymer, and outer layers 2 provided on front and rear surfaces of the central layer 10 and containing a polyolefin-based thermoplastic resin tree, In the thickness direction, two regions in contact with each of the outer layers 2 where the polyolefin-based thermoplastic resin is a continuous phase and the ethylene-vinyl alcohol copolymer is a dispersed phase have a dispersed form in which the regions in which the ethylene-vinyl alcohol copolymer is a continuous phase are held between them.
