Abstract
A wiring board includes a substrate and a mesh wiring layer and has an electromagnetic wave transceiver function. The substrate is transparent. The mesh wiring layer serves as an antenna and includes a wiring line. Two or more opening portions are formed by being surrounded by the wiring line. A planar shape of each opening portion is polygonal that has opposing sides parallel with each other. 95% or more opening portions among 100 opening portions or all of the opening portions satisfy a relationship of 0.70D≤d≤0.98D or satisfy a relationship of 1.02D≤d≤1.30D, where d is distances between sides that extend in a first direction regarding the opening portions, and D is an average value of the distances between the sides that extend in the first direction regarding the 100 opening portions continuously adjacent to each other or all of the opening portions.
