The invention discloses a high-voltage electric energy metering device. A resistance-type high-voltage voltage divider is provided with two parallel plate electrodes; a sheet-type high-voltage arm resistor is obliquely arranged between the two electrodes; an included angle between the high-voltage arm resistor and the electrodes is less than 30 degrees; a high-voltage ceramic capacitor, a high-voltage fuse and a high-voltage damping resistor are connected in series in a capacitance buck power circuit; the high-voltage voltage divider is arranged on the side surface of the high-voltage fuse; the high-voltage capacitor is arranged on the end part of the high-voltage fuse; and the above components are packaged in a cylindrical shell by silicon rubber. The high-voltage electric energy metering device has the advantages of high precision, high temperature stability, low energy consumption and small volume, is safe to use, and is suitable for metering the electric energy of a 6-35kV single-phase, three-phase three-wire as well as three-phase four-wire system high-voltage power line.
