Abstract:
A pointing device includes a first ground potential electrode; a second electrode for applying a voltage; a third electrode for measuring an electrical potential; a printed circuit board on which the first through the third electrodes are provided; a location pointing driving body that is provided on the printed circuit board and that is configured with a conductive part and that contacts the first and second electrodes, and a spherical part; a slide member that is located to cover a top part of the location pointing driving body and that is configured to drive the location pointing driving body by being slidable within a plane parallel to the printed circuit board; and a pressing force restriction member that is configured to restrict pressing force from the spherical part to the printed circuit board by receiving force from the slide member in the pressing direction.
