Claims

[Scope of utility model registration request]

In the vacuum interrupter, the vacuum interrupter is provided with a vacuum container made of an insulator and a metal container, and is provided with an electrode that is placed in the vacuum container and moves toward and away from the vacuum container, and a part of the metal container surrounds the electrode. A first insulating layer with excellent heat resistance is provided on the outer periphery of the metal container at a portion surrounding the electrode, and the metal container and the insulator form a vacuum container with an end of the first insulating layer. A vacuum interrupter characterized in that a second insulating layer having elasticity is provided to surround the vacuum interrupter.
