摘要： The present invention achieves cost reduction by simplifying the manufacturing process for a film-formed molded product provided with a metal coating film capable of transmitting electromagnetic waves therethrough. This method for manufacturing a film-formed molded product which includes a molded product and a metal coating film covering the molded product comprises: forming the molded product between a movable mold and a fixed mold; and then forming the metal coating film which covers the molded product by a film-forming part of a second mold without taking the molded product out from between the movable mold and the fixed mold. The metal coating film is capable of transmitting electromagnetic waves therethrough as a result of generation of cracks after being formed.
