Abstract
To provide a touch sensor board and the like capable of improving the visibility of the screen and the manufacture yield simultaneously. The touch sensor board includes a plurality of mutually parallel first electrodes extended along a first direction and a plurality of mutually parallel second electrodes extended along a second direction. Regarding the first and second electrodes, one of those is connected to each electrode element via a same-layer connection pattern while the other is connected to each electrode element via a different-layer connection pattern. The same-layer connection pattern and the different-layer connection pattern overlap on one another via an interlayer film formed by an insulator. Further, the interlayer film is continued from the overlapping part between the same-layer connection pattern and the different-layer connection pattern via a gap part between each of the electrode elements, and the interlayer film is formed to be continued in the gap part.
