CONSTITUTION:In order to manufacture a plastic injection molding concerned, a transfer sheet having designs 3 is arranged in an injection mold 5 having irregularities 4 so as to perform injection molding. The designs to be transferred are preferably formed by printing 31 by any means such as gravure printing or the like, depositing 32 of metal such as aluminum or the like or the combination of depositing and etching of metal. The optimum transparent or translucent plastic material is acrylic resin. In addition, when fine irregularities 4 are pattern by hairline 42 and designs 3 on the rear side of a part corresponding to said fine irregularities 4 are applied by depositing 32 of metal, the external appearance represented by metal finished by hairline is shown, because the deposited surface is seen through the transparent or translucent plastic.
