Abstract:
1. A multilayer wired board including at least part of an electrical circuit board in which a plurality of wired boards are stacked so as to face their wired surfaces toward each other, comprising: electrical connection parts between said wired boards are connected through a first end of an elastic conductive material part adhered to a first wired board, and a second end of the elastic conductive material part in contact with a second wired board; a double-sided adhesive material part is provided between the plurality of wired boards to adhere them together, and an opening is formed in the double-sided adhesive material part so as to surround at least part of a peripheral edge portion of said elastic conductive material part to seal said plurality of wired boards; wherein a height of said double-sided adhesive material part is smaller than a height of said elastic conductive material part, the second end of the elastic conductive material part and a peripheral part of the second wired board are bent and pressed together, and said elastic conductive material part does not contact said double-sided adhesive material part.
