PROBLEM TO BE SOLVED: To provide a wiring board.SOLUTION: A wiring board includes silver thin wires formed on a substrate by a printing method. The silver thin wire, in a cross section of a direction perpendicular to the wire length direction, is 20 μm or less in width, and 0.013 or more and 0.025 or less in the aspect ratio. The width of the apex becomes smaller than a contact part with the substrate. Surface roughness of the sliver thin wire is 0.25 μm or more and 0.35 μm or less.SELECTED DRAWING: Figure 1 |
