Vacuum interrupter

A vacuum interrupter comprising:

• a fixed-side electrode rod which is fixed to one end portion of a container having a bottomed cylindrical shape;
• a movable-side electrode rod which is movably provided at another end portion of the container;
• a coil electrode which is provided at each of opposed ends of both electrode rods, which are the movable-side electrode rod and the fixed-side electrode rod, and generates a magnetic field in an axial direction, which is a direction along an axis of both electrode rods, by current conduction;
• and a contact portion which is provided on an opposed side of each coil electrode, wherein
• each coil electrode includes
• a ring portion which is concentrically fixed to a corresponding one of both electrode rods,
• a plurality of first coil portions which are disposed so as to be spaced apart from each other in a circumferential direction of the coil electrode by slits,
• a plurality of power feeding portions which are provided at end portions of the plurality of first coil portions, respectively, and
• at least one bypass portion which is provided so as to correspond to at least one of the plurality of first coil portions and connects the corresponding first coil portion and the ring portion, and
• the at least one bypass portion has
• a second coil portion which extends so as to have an overlap with the corresponding first coil portion and the power feeding portion opposed to the first coil portion, in the circumferential direction,
• a first arm portion which connects the second coil portion and the ring portion, and
• a second arm portion which connects the second coil portion and the first coil portion.
