Abstract

A first electrically conductive body and a first solid body are located on the same side of a first base member. A second electrically conductive body is located on a second base member at a position opposed to the first electrically conductive body. A second solid body is located on the second base member at a position opposed to the first solid body. Even when a larger urging force is applied on the second base member, the panel unit allows the first and second solid bodies to receive the urging force. The first and second solid bodies serve to hold the urging force. A predetermined space can thus reliably be kept between the first and second electrically conductive bodies. Establishment of electric connection can be prevented between the first and second electrically conductive bodies. The panel unit keeps normally operating.
