  • Patent number: 10718803
    Abstract: With prior art static electricity distribution measuring devices, there has been the problem that it has not been possible to measure the amount of electrostatic charge over a wide range at high spatial resolution and quickly. In the present invention, there are provided: a detection unit 20 in which a plurality of sensors, provided upon a surface, move relatively along the surface of an electrostatically charged subject 100 to be measured, and detect potential changes generated by the distance to the surface of the measurement subject being changed; a reference distance measuring unit that measures the distance between the surface of the measurement subject and the surface of the detection unit; a distance adjustment unit that adjusts that distance so that it becomes a reference distance that is determined in advance; and a vibrating unit that causes the distance between the surface of the measurement subject and the surface of the detection unit to change upon a predetermined cycle.
