Abstract: A method of fabricating an injection-molded product includes: manufacturing an injection-molded material using a mold; forming a metal layer on an inner or outer surface of the injection-molded material; and removing a portion of the metal layer using a laser, and forming a pattern. Since the injection-molded product fabricated through the method has pattern with a metallic feeling, it can provide a metallic feeling of a high brightness that cannot be realized by a method such as printing and can provide a cubic feeling due to removal of a metal layer. The method provides portable products such as cases for cosmetic products and portable terminals with various visually appealing feelings, allowing users to express various individual styles or preferences using the portable products.
