To suppress cracks generated by a change in environmental temperature in a sensor body of a touch sensor that includes a light-transmissive resin film substantially made of a cycloolefin-based resin. A liquid optically clear adhesive layer is an adhesive layer including a cured body of an adhesive adhering to a glass plate that is a solid member. A sensor body having a film shape firmly adheres to the glass plate by the liquid optically clear adhesive layer, and detects a position of a contact point on a display area. A light-transmissive resin film of the sensor body is substantially made of a cycloolefin-based resin. A buffer layer having viscoelasticity at 25&#xb0; C. is provided between the light-transmissive resin film and the liquid optically clear adhesive layer to relieve stress transferred from the liquid optically clear adhesive layer to the light-transmissive resin film.

Touch sensor and input device

A semiconductor device includes a stacked via structure including a plurality of first vias formed over a substrate, a first interconnect formed on the plurality of first vias, a plurality of second vias formed on the first interconnect, and a second interconnect formed on the plurality of second vias. One of the first vias closest to one end part of the first interconnect and one of the second vias closest to the one end part of the first interconnect at least partially overlap with each other as viewed in the plane, and the first interconnect has a first extension part extending from a position of an end of the first via toward the one end part of the first interconnect and having a length which is more than six times as long as a via width of the first via.
