Abstract:
1. A force detector comprising: a plate-like first member; a plate-like second member provided with a gap between the first member and the second member; an elastic member that has first and second surfaces opposite to each other and that is provided between the first member and the second member, the first and second surfaces respectively face the first and second members; and a plurality of pressure-sensitive devices provided between the elastic member and the second member, wherein an area S each of the plurality of pressure-sensitive devices includes: the divided two electrodes, the pressure-sensitive conductor layer and the single common electrode are directly stacked between the elastic member and the second member so that the second surface of the elastic member directly contacts the divided two electrodes and the single common electrode directly contacts the second member, the plurality of pressure-sensitive devices are evenly located in point symmetry with respect to a center of the first member, and the second gap is located on an imaginary radial linear line extending from the center of the first member in the plan view.
