1. An electrode structure comprising:
a base material;
a conductive fabric on a first surface of the base material; and
one or more conductive wires on a second surface of the base material so as to be electrically insulated from the conductive fabric, the second surface being opposite to the first surface of the base material, wherein
the base material includes a first area and a second area, the first area of the base material being fitted into a groove of a rim of a steering wheel and the second area of the base material being placed along a part of the rim other than the groove when the base material is attached to the rim,
the one or more conductive wires are arranged to extend over the first area and the second area, and
the one or more conductive wires are arranged at a lower wiring density in the first area than in the second area.
