Title:
INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146372
Kind Code:
A1
Abstract:
An input device with which the edge effect at an end surface of an adhesive layer can be reduced and damage to an electrode can be suppressed when a film sensor is attached to a convex surface, said input device comprising a film sensor and a cover member having a convex surface. The film sensor has: a supporting base material having a film-like main body section and an extended section extending outward from the edge of the main body section; a plurality of electrode parts provided on a surface of the main body section; and a lead-out pattern electrically connected to each of the plurality of electrode parts, and extending from the main body section toward the extended section. The surface of the main body section on which the plurality of electrode parts is located is attached to the convex surface, with an adhesive layer therebetween. The adhesiveness of an end-portion adhesion region located on the extended-section side of the adhesive layer is lower than the adhesiveness of a center-portion adhesion region located toward the center portion of the convex surface in the adhesive layer.
