Abstract
A load sensor includes: a first base member and a second base member disposed so as to face each other; an electrically-conductive elastic body disposed on an opposing face of the first base member; a wire member that is electrically conductive and disposed between the second base member and the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the wire member. The dielectric body has a stress relaxation part for releasing stress applied to the dielectric body during load application.
