体としてシワが発生し難くなる。According to the present invention, the decorated sheet is sandwiched between the molds to be ready for injection. Originally, the picture-added sheet at a position far from the gate accumulates distortion, and therefore wrinkles increase. Conversely, the picture-added sheet sandwiched near the gate has less distortion and less wrinkles. Therefore, since the clearance is increased at the position far from the gate, the picture-added sheet slips slightly and wrinkles are reduced. Therefore, the wrinkles near the gate and the positions far from the gate are balanced, and the wrinkle is less likely to occur in the entire painted sheet.

When the injection resin is poured from the gate 4 provided in the female die 1 in this state, the injection resin sequentially flows toward the facing end surface while pressing the decorative sheet S. Now, when the notch (step) is not formed in the female mold, wrinkles of the picture-added sheet during molding are more likely to occur at positions farther from the gate position where the picture-added sheet is distorted. That is, the wrinkles of the painted sheet are more likely to occur at positions where the influence of the injection pressure is less likely to occur. Therefore, the clearance is increased at a position far from the gate so that the picture-added sheet is slippery. Then, the wrinkles of the film caused by the shearing of the injection resin are less likely to occur at the position far from the gate.
