1. A Vacuum interrupter comprising:
a pair of electrodes comprising electrode opposed surfaces, respectively, and provided such that the electrode opposed surfaces face each other, the electrodes being allowed to be separated from and connected to each other; and
an undulating structure provided in each of the electrode opposed surfaces or in one of the electrode opposed surfaces, wherein
the undulating structure comprises:
one or more projections which project from the electrode opposed surface such that the electrode opposed surface has a regular concavo-convex shape extending in a predetermined direction; and
depressions provided so as to be adjacent to the projections, respectively,
the projections and the depressions are alternately provided when viewed in a direction crossing the electrode opposed surface, and
in a conducting state in which the electrodes are in contact with each other, the projections are in contact with the opposite electrode opposed surface, and the depressions are not in contact with the opposite electrode opposed surface.
