Abstract: In a touch sensor in which a touch sensor body is attached to a cover member, the cover member includes: a first member made of a glass plate and having a first surface and a second surface that is an opposite surface of the first member from the first surface; and a resin film made of polyvinyl butyral (PVB) and formed on the second surface. The resin film is located between the first member and the touch sensor body.

Abstract: A touch panel includes a light-transmitting cover lens, a sensor portion, and a first adhesive layer. The first adhesive layer bonds the cover lens and the sensor portion to each other. The first adhesive layer has a storage elastic modulus at 90° C. of 68 kPa or more and 200 kPa or less. When a surface of the cover lens, being in contact with the first adhesive layer, is a bonding surface, a water contact angle on the bonding surface of the cover lens is more than 0° and 59° or less.
