Abstract
Provided is a touch panel having a curved surface. A touch panel 10 is formed of a sheet of a flat sheet 1 by thermoforming. A plurality of island-like electrodes 2,3 is arrayed in each of an X direction and a Y direction on the input region. The island-like electrodes 2, 3, inter-electrode wires 4, and a lead wiring are formed of a ductile wire material. A center portion of the flat sheet 1 is formed into a convex dome shape by thermoforming. The touch panel 10 includes a first input region 11 and a second input region 12. The first input region 11 is provided on the convex dome shape. The second input region 12 is provided on the flat surface (zero curvature). The first input region 11 is provided at around a center on the inside of the second input region 12.
