Provided are: a plurality of transmitting electrodes each extending in a first direction and spaced apart in a second direction orthogonal to the first direction; a plurality of receiving electrodes each extending in the second direction and spaced apart in the first direction; a plurality of first wires each electrically connected to one corresponding transmitting electrode included in the plurality of transmitting electrodes; and a plurality of second wires each electrically connected to one corresponding receiving electrode included in the plurality of receiving electrodes. The shortest transmitting electrode disposed at an end and the shortest receiving electrode disposed at an end do not overlap with each other in plan view.

Touch sensor

A touch panel includes a transparent plate, an upper substrate having an upper surface situated on a lower surface of the transparent plate and stacked on the transparent plate in a downward direction, an upper conductive layer provided between the lower surface of the transparent plate and the lower surface of the upper substrate, a lower substrate having an upper surface situated on the lower surface of the upper substrate and stacked on the upper substrate in the downward direction, and a lower conductive layer provided between the lower surface of the upper substrate and the upper surface of the lower substrate and facing the upper conductive layer across the upper substrate. The upper surface of the transparent plate has a dome shape projecting upward on a cross section in a first direction perpendicular to the downward direction and on a cross section in a second direction perpendicular to the downward direction and the first direction. The lower surface of the transparent plate is concave upward on the cross section in the first direction is straight on the cross section in the second direction. The touch panel can be easily manufactured and reliably operated.
