First Claim
1. A touch panel comprising:
- a first substrate being light-transmittable and having a first surface and a second surface opposite to the first surface, the first substrate having a first outer periphery;
a first resistance layer being light-transmittable and provided on the first surface of the first substrate;
a second substrate being light-transmittable and having a third surface and a fourth surface opposite to the third surface, the second substrate having a second outer periphery;
a second resistance layer being light-transmittable provided on the third surface of the second substrate, the second resistance layer facing the first resistance layer by a predetermined gap between the second resistance layer and the first resistance layer;
a spacer having substantially a frame shape provided between the first outer periphery of the first substrate and the second outer periphery of the second substrate;
a first adhesive layer provided on the fourth surface of the second substrate, the first adhesive layer having an adhesion property;
a sheet being light-transmittable and having a fifth surface and a sixth surface opposite to the fifth surface, the fifth surface of the sheet being attached onto the first adhesive layer; and
a second adhesive layer provided on the sixth surface of the sheet, the second adhesive layer having an adhesion property weaker than the adhesion property of the first adhesive layer.

Abstract
A touch panel includes a first substrate, a first resistance layer on a surface of the first substrate, a second substrate, a second resistance layer on a surface of the second substrate, a spacer having substantially a frame shape provided between outer peripheries of the first and second substrates, a sheet having a surface attached to the surface of the second substrate with a first adhesive layer, and a second adhesive layer on the surface of the sheet. The second resistance layer faces the first resistance layer by a predetermined gap between the second and first resistance layers. The second adhesive layer has an adhesion property weaker than that of the first adhesive layer. This touch panel can be attached onto a display element again easily.
