A conductor detecting switch is provided in which the occupied area on an operating panel can be reduced and high detection sensitivity to a conductor can be realized even when the occupied area is thus reduced. An electrode provided on a control board, and a control IC chip having an electrostatic capacity detector circuit for detecting electrostatic capacity stored in the electrode are provided on the inner side of an operating panel. On the electrode, an LED, which is a dielectric member, and a dielectric member made of synthetic resin are provided to overlap each other. The control board is attached to the inner side of the operating panel, sandwiching the dielectric member between them.
