A vacuum interrupter for improving productivity according to an embodiment of the present invention includes a fixing electrode; a moving electrode which is moved by a driving part and is attached to or detached from the fixing electrode; a ceramic container which accommodates the fixing electrode and the moving electrode and forms a lateral surface; a seal cup of a fixing side which supports the fixing electrode and is installed between the fixing electrode and the ceramic container to keep a vacuum sealing state; and a seal cup of a moving side which supports the moving electrode and is installed between the moving electrode and the ceramic container to keep the vacuum sealing state. The seal cup of the fixing side comprises a plane part which is extended from one end of the fixing electrode, an inside wrinkle part which is firstly bent from the plane part downwards and then bent upwards, and an outside winkle part which is extended from the inside winkle part upwards to be bent to the outside and then bent downwards. |
