A vacuum switch is provided with a vacuum valve 1 including a stationary-side terminal conductor 3 and a moving-side terminal conductor 16 . In the vacuum switch, a radiator 29 provided with a cover 37 making open a side face of a plurality of fin-shaped protrusions 36 extending outwardly from the terminal conductor 3, 16 and surrounding an outer periphery, is fixed to the terminal conductor 3, 16. Furthermore, the plurality of fins 43 including a cover 42 making a side face open and surrounding an outer periphery is integrally molded on the terminal conductor 3, 16. As a result, a vacuum switch is capable of making smaller an air clearance between the radiator and a peripheral housing.
