Abstract
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° 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.
