A vacuum interrupter for opening and closing a current passage comprises a pair of electrodes which are detachable and respectively connected to each of conductive rods in a vacuum container, wherein each of said electrodes comprises one or more grooves to cut the peripheral part of the electrode at one end and to approach the other end near the peripheral part of the electrode to form a current passage and also each current conductor connecting electrically said electrode to said conductive rod near the cut part of said electrode deviated from the center of said electrode, whereby a magnetic field in parallel to the arc between said pair of electrodes is formed.
