Electromagnetic wave transmissive cover and method for manufacturing the same

A method for manufacturing an electromagnetic wave transmissive cover to be installed on a vehicle in an electromagnetic wave irradiation direction of a sensor using an electromagnetic wave, the method comprising:

• forming a wiring pattern having a wiring width of 50 to 70 μm by copper plating or copper foil etching on a base substrate to prepare a transparent heater film;
• molding a colored resin member having a first surface with a three-dimensional shape;
• and
• molding a transparent resin member having a second surface with a three-dimensional shape on the first surface of the colored resin member, and integrally molding the transparent heater film having electromagnetic wave transmissivity with the transparent resin member on an outermost surface of the transparent resin member opposite the second surface with the three-dimensional shape,
• wherein the transparent heater film further includes a cover layer and the base substrate, such that the wiring pattern is provided between an upper surface of the base substrate and a lower surface of the cover layer.
