WIPO Patent Application WO/2018/147424
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a printed wiring board in which the electrical resistance value between a reinforcing member and the ground circuit of the printed wiring board does not readily increase. This printed wiring board includes a substrate film in which a printed circuit including a ground circuit is formed on a base film, an adhesive layer formed on the substrate film, and an electroconductive reinforcing member formed on the adhesive layer, wherein the printed wiring board is characterized in that: the adhesive layer contains electroconductive particles and an adhesive resin; and a first low-melting-point metal layer is formed on the electroconductive particles, or a second low-melting-point metal layer is formed between the substrate film and the adhesive layer, or a third low-melting-point metal layer is formed between the adhesive layer and the reinforcing member.
