Abstract: PURPOSE:To provide a high-voltage generating device wherein a high voltage can be generated effectively, by fusing its electrical and mechanical configurations. CONSTITUTION:In each stage of a high-voltage generating device, on the peripheral edge of a rotational disk, a plurality of metallic pellets 6 are arranged, and in close proximity thereto and oppositely thereto, a plurality of fixed electrodes 7 are arranged on an annular body. The fixed electrode 7 is connected with a multiplying rectifier circuit comprising a rectifying element and a capacitor.

Each induced AC voltage is rectified by the multiplying rectifier circuit, and the capacitor of each multiplying rectifier circuit is charged with the multiplied voltage. The parts of a ground potential and a high potential are connected by the respective capacitors connected in series with each other. Therefore, the multiplied voltages with each of which the capacitor is charged every the fixed electrode 7 are added to each other between the parts of the ground potential and the high potential, and the added voltages in the respective stages are further added to each other, and as a result, a high voltage can be obtained in the high-potential part.
