Recently, manipulation techniques for handling a conductive small-particle have been in demand. Electrostatic manipulation with a single probe is a promising technique for such manipulation. In this study, the force worked between the upper hemisphere electrode and ball is studied. The force worked on the ball is analyzed. It is found that when the diameter of hemisphere is decreased, the force decreases, and that the voltage for catching ball increases as the humidity increased. It is confirmed that the ball is caught by the hemisphere electrode covered by dielectric film.
