Abstract
In a touch sensor, a wiring board has signal line portions electrically connected to a first sensor terminal of a first sensor board at a first end; a ground portion electrically insulated from the signal line portions; and an insulating layer covering the ground portion. The insulating layer has a plurality of through holes for passing through the insulating layer in a thickness direction of the wiring board and exposing the ground portion therethrough. The plurality of through holes are arranged at intervals. A line segment connecting two through holes of the plurality of through holes intersects the plurality of signal line portions.
