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.

Touch sensor

A first member of a cover member includes an operation portion disposed so as to correspond to a position where a sensor body is attached and having a sensor region (T) of substantially the same size as a sensor unit on the front side of the operation portion, and a design connection portion that is continuous with a side part of the operation portion and that has a surface formed so as to be continuous with a contoured surface of a wall and curved with a smaller radius of curvature than a surface shape of the operation portion.

Touch panel and design structure provided with same

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&#xb0; 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&#xb0; and 59&#xb0; or less.

Touch panel

A touch panel includes a first substrate, a first reflection conversion layer formed on the first substrate, multiple belt-like first conductive layers formed on the first reflection conversion layer, and a first adhesive layer formed on the first conductive layers. The touch panel further includes a second substrate formed on the first adhesive layer, a second reflection conversion layer formed on the second substrate, multiple belt-like second conductive layers formed on the second reflection conversion layer in a direction perpendicular to the first conductive layers, a second adhesive layer formed on the second conductive layers, and a cover sheet disposed on the second adhesive layer. Pigment is dispersed in at least one of the first adhesive layer and the second adhesive layer.

A touch panel includes a cover substrate, an upper resin layer, upper conductive layers, a lower resin layer, lower conductive layers, and a protective layer. The upper conductive layers are in contact with the upper resin layer on the side opposite to the cover substrate. The lower resin layer is in contact with the upper conductive layers and the upper resin layer. The lower conductive layers are provided on the side of the lower resin layer opposite to the upper conductive layers with the lower resin layer placed between the lower conductive layers and the upper conductive layers. The protective layer is provided on the surface of the lower resin layer on which the lower conductive layers are formed. Each of the upper resin layer and the lower resin layer is formed of a uniform material.

Touch panel and method of producing the same

A mesh sheet of the present invention is a mesh sheet in which a metal mesh comprising fine bands is laminated on a surface of a base substrate, the mesh sheet being used and adhered along a surface of an arbitrary member having a curved surface portion. The metal mesh has a part in which the fine band positioned between connection points of the fine bands which are adjacent to each other is a curved line so as to absorb stress relative to deformation to be placed along the curved surface portion with a large curvature without destructing the metal mesh.
