Abstract:
1. A touch panel comprising: a first substrate having a first principal plane that is a top surface and a second principal plane that is a bottom surface on which a first transparent conductive film is formed; a second substrate having a third principal plane on which a second transparent conductive film is formed and a fourth principal plane; and a bonding portion that bonds together the first substrate and the second substrate to integrally form the first substrate and the second substrate, wherein the first substrate and the second substrate are disposed so that the first transparent conductive film and the second transparent conductive film are opposed to each other; the first substrate is a glass substrate made by a float glass process and is warped to be convex from the second principal plane toward the first principal plane; and when an operational input is not provided to the touch panel, the first substrate is supported only by the bonding portion above the second substrate.
