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; an electrically-conductive member having a linear shape 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 electrically-conductive member. The electrically-conductive member has a bent shape that is bent in a direction toward the electrically-conductive elastic body.

Abstract: A load sensor includes: 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. A plurality of projections are formed on a surface on the dielectric body side of the electrically-conductive elastic body, and the thickness of the dielectric body decreases in the plane direction from an initial contact position with respect to the electrically-conductive elastic body.

Abstract: A load sensor includes: an electrode; a dielectric formed on a lower surface of the electrode; and a conductive elastic body disposed so as to face a lower surface of the dielectric and having conductivity. A plurality of projecting portions are formed on an upper surface of the conductive elastic body. The conductive elastic body has a bending shape that is bent in an up-down direction, in at least a part thereof. Alternatively, at least either the conductive elastic body or the electrode has a bending shape that is bent in an up-down direction, in at least a part thereof.
