A method for producing a thermoplastic resin molded article comprises steps of (a) supplying a first molten thermoplastic resin from a first resin-supplying gate to a first portion of a cavity formed between a cavity face of a first mold and a cavity face of a second mold, said first and second molds being in an open state; (b) closing said first mold and said second mold to set the cavity in a closed state; (c) injecting a second molten thermoplastic resin from a second resin-supplying gate to a second portion of the cavity in the closed state; (d) cooling and solidifying said first and second resins in the cavity in the closed state; and (e) opening said first mold and said second mold to remove said molded article. A resin molded article having a uniform surface and an excellent outer appearance can be efficiently and easily produced under a relatively low pressure while preventing luster variations or wrinkles at a portion of the surface of a desired molded article, which portion requires an excellent outer appearance or has a designed surface.
