PROBLEM TO BE SOLVED: To provide a method for molding first and second molded articles in one mold at the almost same period to integrate both of them. SOLUTION: A parting cavity 9 is formed between a slide mold 10, which is present at an advance position in the mold clamping state of first and second molds 5, 6, and a ridge part 8 and, subsequently, a first resin material is injected in a first cavity 7a and a second resin material is injected in a second cavity 7b and the injection period of the first and second resin materials is set so that the first and second resin materials arrive at the parting cavity 9 almost at the same time and, after the resin materials arrive at the parting cavity 9, the slide mold 10 is allowed to retreat not only to increase the volume of the parting cavity 9 but also to fill the parting cavity 9 with the resin materials to obtain an injection-molded article wherein first and second molded objects 2,3 are integrally molded at a parting part 4.
