れた美しいものになる。As a method of providing a transparent portion, there is a method of using an insert sheet having a transparent portion and a concealing portion and integrally forming a transparent resin molded product on the entire back surface of the insert sheet (see FIG. 5). Since the transparent resin molded product is also integrally formed on the back surface of the transparent portion, the transparent portion is excellent in transparency, and the surface of the resin molded product is beautiful with a faithful reproduction of the mold shape.

成されないようにする方法がある（図６参照）。Further, an opaque resin molded product is integrally formed only on the back surface of the concealing portion using an insert sheet having a transparent portion and a concealing portion so that no resin molded product is formed on the back surface of the transparent portion. There is a method (see FIG. 6).

Due to the fact that the insert sheet is configured to cover the entire part of the injection-molded transparent resin molded product, when obtaining a molded product with a large side rise, the elongation of the insert sheet cannot follow the shape of the resin molded product Therefore, there is a drawback that the insert sheet is wrinkled or misaligned.

う欠点があった。In the latter case, a hole is formed in the opaque resin molded product as a result of preventing the opaque resin molded product from being formed on the back surface of the transparent portion of the insert sheet. However, when the insert sheet is integrated simultaneously with the molding, when the molding resin is molded, taken out of the mold and allowed to cool in the air, the molded article undergoes resin shrinkage but the insert sheet does not. For this reason, the transparent portion of the insert sheet sags, causing a problem that the liquid crystal display or the like appears distorted. Also, when obtaining a molded article with a large rise, as in the former method,
Since the elongation of the insert sheet is insufficient, there are drawbacks in that the insert sheet is wrinkled or misaligned.
