PROBLEM TO BE SOLVED: To solve the following problem: when injection molding and decoration are applied simultaneously on both surfaces of a molding, in demolding from a mold, ejection by an ejector pin is difficult due to the presence of a decorative sheet. SOLUTION: As regards a mold for simultaneous decoration and injection molding, a first decorative sheet 2 is mounted on a mold A 5, after a second decorative sheet (second decorative layer 30) is mounted on a mold B, a molding space part is formed by clamping the mold A and the mold B, and a molding resin is injected into the space part to form an injection-molded article, integrating the first decorative sheet and the second decorative sheet. The ejector pin 4 is set at a position different from the first decorative sheet mounting part of the mold A, and a part of the space part is contacted with the tip part of the ejector pin of the mold A. In this way, even when the first decorative sheet is mounted, the ejector pin can be operated without being affected so that a simultaneously molded/decorated molding can be easily removed from the mold A.
