Abstract: This invention relates to an electrostatic high-voltage generator in which an electrostatic charge is transported mechanically and is stored on a high-voltage electrode, and plural layers of charge carrier unit for carrying electrostatic charges, are stacked in a direction at right angles with the direction of carrying the charge, and there is provided between respective adjacent ones of those charge carrier units, a charge carrying transfer means for carrying an electric charge carried to the adjacent charge carrier unit. The apparatus can generate an ultra high-voltage and can be constructed economically into a small-sized one.
