Patent ID: 8237057

Claim:
A wiring board that has a plurality of layers, comprising: a first wiring pattern that includes electrically conductive nanoparticles as a principal material and is formed in a soluble porous membrane member of any single layer; and a second wiring pattern that does not include the electrically conductive nanoparticles as a principal material, wherein a single layer among the plurality of layers is an electrically insulative substrate; an another single layer among the plurality of layers is a porous membrane member layer that includes the porous membrane member in all or one part of a region of the another single layer; the first wiring pattern is formed in the porous membrane member layer; the second wiring pattern is formed on at least any one surface of the substrate; the wiring board is bent around a bending section; and the porous membrane member layer is formed using the porous membrane member that is provided at parts excluding a vicinity of the bending section.
