Abstract: An electrode for a vacuum circuit breaker comprises a cylindrical conducting body, a contact electrode as a combination electrode, and a plurality of slits provided on a surface area of the cylindrical conducting body, the slits being inclined with respect to an axial direction of the cylindrical conducting body, wherein an angle between the slits and the axial direction of the cylindrical conducting body is smaller as the slit becomes farther away from the contact electrode.
