PURPOSE:To provide a method of manufacturing efficiently a molded item, which is used as a circuit component in the field of an electrical apparatus, an electronic equipment and the like and has an accurate conductive circuit on the surface. CONSTITUTION:In a method wherein a metal thin film formed on the surface of a synthetic resin molded item is irradiated with laser beam, the metal thin film is removed to conduct the formation of a circuit pattern and a circuit is formed by electroplating, the thickness of the metal thin film is set in a thickness of 0.2 to 2.0mum and is the metal thin film formed on the surface of the molded item to remove the metal thin film in a width of 100 to 500mum is irradiated with the laser beam having a laser spot diameter of 50 to 500mum. |
