あり之。(Conventional technology) In recent years, as equipment has become smaller and more compact, plastic molded products are being used as housings for various convenience computers, digital devices, etc. There is a need for effective electromagnetic shielding technology against electromagnetic waves.For this reason, conductive plastics containing carbon or metal fibers have been researched, and they have also been shown to have good shielding effects for TFB waves in plate-shaped molded products. However, in this method, a large amount of filler must be mixed in order to obtain the full effect of good electromagnetic wave shielding, which has drawbacks such as poor appearance and reduced strength.

い友。(Problems to be Solved by the Invention) However, in the conventionally proposed products with integrated four-conductive knitted fabrics, the metal layer of the conductive knitted fabric exposed on the surface of the molded product is in close contact only with the knitted fabric. Because of this, adhesion is a problem, and in practice there is a concern that a piece of metal that has peeled off may fall onto the circuit, causing a backlash problem. One way to improve the layer density of the metal layer is to laminate a conductive knitted fabric and a thermoplastic film, and then create an integrated bottom structure in which the conductive knitted fabric is sandwiched between the thermoplastic film and the molded product. A method has also been proposed to obtain the product, but the problem is that the thermoplastic film surface is an insulator and the ground cannot be taken out.
