Abstract:
1. A resistive sheet comprising: a flexible cover sheet; a wiring part including a conductive metal wire, the wiring part being provided on a bottom face of the cover sheet; a resistive layer connected to the wiring part, the resistive layer having one of ring, circular-arc, and spiral shapes, and an uneven bottom face; and a spacer layer whose bottom face is disposed at a position lower than the resistive layer; wherein the resistive layer includes first and second resistive layers, the first resistive layer being disposed on a bottom face of the wiring part, and the second resistive layer being disposed on a bottom face of the first resistive layer, such that the first resistive layer is disposed between the wiring part and the second resistive layer; wherein a sheet resistance of the second resistive layer is greater than a sheet resistance of the first resistive layer; wherein the second resistive layer has an uneven bottom face; and wherein the wiring part is sandwiched between the spacer layer and the bottom face of the cover sheet.
