According to an aspect, a force sensor includes: a plurality of first electrodes that are arranged along a substrate; an elastic body that is in contact with the first electrodes; a second electrode that is in contact with the elastic body, the elastic body being interposed between the second electrode and the first electrodes; and a third electrode that is provided on the substrate side of the second electrode and configured to be electrically coupled to the second electrode. The elastic body includes a conductive particle that electrically couples the first electrodes and the second electrode when force is applied that causes the first electrodes and the second electrode to be approached. The third electrode has a continuous lattice shape that separates at least the first electrodes adjacent in one direction from each other.
