1. A load sensor comprising:
an electrode;
a dielectric body disposed on a surface of the electrode; and
an electrically-conductive elastic body having electrical conductivity and disposed so as to be opposed to the dielectric body, wherein
a plurality of projections are formed on a surface on the dielectric body side of the electrically-conductive elastic body, and
a thickness of the dielectric body decreases in a plane direction from an initial contact position with respect to the electrically-conductive elastic body.
