Abstract:
1. An optical-electrical wiring board, comprising: a substrate; a dielectric layer disposed on a main face of the substrate, the dielectric layer comprising a first region and a second region, the dielectric layer configured to constitute a plurality of light transmission portions in the first region; and a plurality of pairs of electrically conductive layers located at the second region, wherein a plurality of overlap portions are provided in which conductive layers constituting each pair of the plurality of pairs of electrically conductive layers overlap each other, when viewed in a laminated direction of the dielectric layer and the substrate, the laminated direction being perpendicular to the main face of the substrate, the dielectric layer further comprises a third region that is located such that the second region is disposed between the third region and the first region, and the plurality of overlap portions extend from the third region toward the first region, and a distance between two adjacent overlap portions of the plurality of overlap portions increases as the two adjacent overlap portions approach a side of the first region, when viewed in the laminated direction.
