<p>PROBLEM TO BE SOLVED: To provide a wiring board 101 for achieving an invisible state of a metallic wiring M1.SOLUTION: A wiring board 101 includes a transparent base material 9 and a circuit pattern 1 formed on the base material 9. At least a part of the circuit pattern 1 is a metallic wiring M1. A light extinction layer 5 is formed on the metallic wiring M1. The light extinction layer 5 is formed with the concentration distribution of optical density (OD value) and a contour of the light extinction layer 5 is formed in a curve having the irregularities.</p> |
