The invention is to provide an electronic survey device for equalizing the electron irradiation a certain direction in the irradiated portion of the plane. By connecting a direct current power source (1) of the battery 6V direct current type high-voltage unit (2), by a DC-type high voltage equipment (2) steps up the power of minus 6V to 5500V. Wiring the negative output terminal (3) of the direct current type high-voltage unit (2) to the cathode electrode 5, and wiring the positive output terminal 6 of the DC high voltage source (2) to the anode electrode 7. The close contact with the dielectric sheet 4 with appropriate relative permittivity and volume resistivity of a range on the opposite side of the anode electrode (7) of the cathode electrode (5). The dielectric sheet 4 is formed of a sheet of polyurethane rubber. Adhered to the cathode electrode 5 and the dielectric sheet 4 constitutes a DC-type dielectric barrier discharge electrode 9 of the present invention. Mounting the belt-shaped arrangement to obtain a driving power source (1) and the high-voltage direct-current type (2) on the top surface of 15, and place the discharge electrode 9 and anode electrode 7 on the bottom. When winding the mounting holes 15 to the return of the blood to the therapist, it is placed opposite the affected part between the electrodes (9, 7).
