効果をも発揮することもできる。According to the method for manufacturing a partially decorative molded product of the present invention, a metal mold having a convex portion having a width of 0.1 to 4 mm and a height of 0.1 to 3 mm is used. Since it is aligned with the convex part of the mold, in the obtained partially decorative molded product, the peripheral edge of the decorative film is formed on the inner surface of the groove of the molded product formed by the convex part of the mold. Since the groove of the molded product is deep and relatively dark, the peripheral edge of the decorative film is inconspicuous. For this reason, it is difficult to discriminate and visually recognize a cutting trace of the peripheral portion of the decorative film, a waving at the time of cutting, a positional shift or a distortion of the peripheral portion due to the contraction of the decorative film, and the design has a good appearance. In addition, the peripheral portion of the decorative film comes into contact with the convex portion of the mold or covers the convex portion of the mold. Therefore, even if the decorative film is likely to be swept away by the injected molten resin, the decorative film is caught by the convex portion and is not easily washed away. For this reason, the position of the decorative film once positioned does not shift. Therefore, the appearance is good in design. Furthermore, since the boundary of the surface state between the portion where the decorative film is present and the base portion of the molded product is emphasized and expressed, it looks as if different parts are fitted together with the groove as a boundary. Etc., it can also exhibit pseudo-design effects.
