PURPOSE: An electrode for vacuum interrupter is provided to increase the axial magnetic flux density without extending the separation distance between two coil conductor parts. CONSTITUTION: The coil conductor forms the axial magnetic flux. The first counter electrode board(250) is installed on the top of the coil conductor. The second supporting electrode plate is installed in the lower part of the coil conductor. A plurality of support pins is connected for the first counter electrode board and coil conductor between the second supporting electrode plate and coil conductor. The mechanical strength is reinforced. A plurality of conductive pins(280a-280d) is connected for the first counter electrode board and coil conductor between the second supporting electrode plate and coil conductor.
