    • A vacuum interrupter of parallel magnetic field electrode type comprising a pair of separatable arc electrodes disposed within a vacuum vessel, with each being provided on its back side with a conductive rod extending outwardly of the vacuum vessel. Coil electrodes are electrically connected between the associated arc electrode and rod for applying parallel magnetic fields to arc, and slits are formed in the arc electrodes for suppressing eddy currents of the arc electrodes resulting from the parallel fields. A reinforcement member of an electric conductivity higher than a main surface portion of the arc electrode is provided on the back side of the arc electrode opposite to said main surface portion so that the resulting arc current flows uniformly through the reinforcement member so that a higher interruption efficiency can be obtained for the vacuum interrupter.
