Abstract
A manufacturing method of a film insert molded article in which no resin layer is seen in the front and no wrinkle is generated in a film is provided. A thermoformed film (11) for coating is arranged within a cavity (15), and molten resin is injected so that a film insert molded article (50) molded integrally with the film (11) for coating and having a coating plane coated with the film (11) for coating is obtained. A printing ink layer (20) and a binder layer (30) are formed in a raw material film (10). The raw material film (10) is cut out and the film (11) for coating is formed so as to have a size for coating the coating plane and being able to form an outer circumferential bending portion (12) arranged in an outer circumferential side portion (41) by adding a width exceeding a heat shrinking amount of the film. After the film (11) for coating is preheated, the film (11) for coating is thermoformed so that a predetermined three-dimensional shape (13) and the outer circumferential bending portion (12) are formed. The film (11) for coating in which the three-dimensional shape (13) and the outer circumferential bending portion (12) are formed, is arranged within the cavity (15) su…
