PROBLEM TO BE SOLVED: To provide a method for reducing pressure required for the injection of a resin for a core, and also, for increasing a core filling ratio in the method for manufacturing a sandwich-molded article by connecting two injection units to a mold. SOLUTION: In the fixed mold 5 and the movable mold 6, a recess section 7 is formed on one mold surface, and a protruding section 8 is formed on the other mold surface. A cavity is formed between them by fitting the protruding section 8 in the recess section 7, and also, the depth for the fitting can be changed. The relative position of the movable mold 6 to the fixed mold 5 is set at a first position, and the injection of a resin 21 for the skin is started into the cavity. Then, after starting the injection of a resin 22 for the core into the cavity, the advancing motion of the movable mold 6 to the fixed mold 5 is started. Then, after stopping the injection of the resin 22 for the core, the advancing motion of the movable mold 6 is stopped. In the end, the injection of the resin 21 for the skin is stopped.
