Abstract
In an electrostatic capacitance sensor, an electrode is formed on a base board. The electrode is covered with a resist. A conductive rubber includes a first face and a second face. The first face has a first area and is opposed to the resist. The second face is opposed to the first face. The second face has a second area which is larger than the first area. A flexible click rubber is attached on the second face of the conductive rubber for providing pressure contact of the conductive rubber with respect to the resist.
Claims6
