Object There is provided a molded article or an electrical product in which layout of a member up to an external connection terminal for electrical connection of a circuit film integrally molded with the molded body is easy. Solution means A molded bodyincludes one main surfacewith which a circuit filmis integrally molded, and another main surfacefacing the one main surface. A flexible printed wiring boardincludes an internal connection terminalelectrically connected to an electrical circuit of the circuit film, an external connection terminalexposed outside from the other main surfaceof the molded body, and a flexible wiring lineconnected to the inner connection terminaland the external connection terminal, passing through an inside of the molded body, and extending so as to reach the other main surface

Molded article, electrical product and method for producing molded article

In a first step, a circuit sheet is set such that a first region of a second main surface of the circuit sheet is in contact with a plateau portion of a first mold and a second region is not in contact with the first mold. In the first step, a first fixed portion of the circuit sheet is arranged on a first portion of the first mold, and a second fixed portion is arranged on a second portion of the first mold. The first portion is a portion that is higher than the plateau portion and runs along at least one of a first protruding portion and a second protruding portion provided along the plateau portion. The second portion is a portion where the first protruding portion or the second protruding portion is not provided along the plateau portion.

Molded article and method for manufacturing molded article

A molded product and an electrical product comprising a molded article that includes a main body made of resin and a standing wall made of resin. The standing wall integrally stands up from the end portion of the main body. A decorative sheet includes a base film and a conductive circuit layer. The base film continuously covers from the main body front surface to a wall front surface. The conductive circuit layer is disposed between the base film and the main body front surface. The decorative sheet is integrated with the molded article to implement a decoration with the base film. A flexible printed circuit board is disposed between the molded article and the conductive circuit layer. The flexible printed circuit board is partially embedded into and integrated with the standing wall. The flexible printed circuit board is electrically connected to the conductive circuit layer.

Molded product, electrical product, and method for manufacturing molded product

A composite molding comprises an insulative molded body molded into a prescribed shape; an insulative transfer layer covering at least part of a front surface of the molded body; an electrode pattern layer formed between the molded body and the transfer layer; an electrically conductive contact pin having one end side buried in the molded body and fixed thereto and an other end stuck out from the molded body; and an electrically conductive bonding agent formed between the electrode pattern layer and the molded body and bonding to the electrode pattern layer and the contact pin to form an electrical connection between the electrode pattern layer and the contact pin. This arrangement prevents defects caused by embedding a contact pin in a molded body and reliably makes an electrical connection between the contact pin and an electrode pattern layer.

Composite molding and method of manufacturing the same

An injection molded product in which an electrical connection between a contact pin and an electrode pattern is sufficient, and a method of manufacturing the same, are provided. The injection molded product comprises: a base film; an electrode pattern, which is formed on the base film; an electrically conductive adhesive, which is formed on an upper surface of the electrode pattern; a contact pin, which contacts the electrically conductive adhesive, is electrically connected to the electrode pattern via the electrically conductive adhesive, and is electrically conductive; and a molded resin, which is injection molded along the base film such that the electrically conductive adhesive and part of the contact pin are embedded.
