PROBLEM TO BE SOLVED: To provide a contactor capable of swiftly eliminating electric-arc.SOLUTION: The contactor includes: a fixed contact 10; a movable contact 11 which is movable between a close position at which movable contact 11 comes into contact with the fixed contact 10 and an open position separated away from the fixed contact 10; and an arc eliminator 14 having a hydrogen storage metal which emits hydrogen, which is disposed in a space identical to that of the fixed contact 10 and the movable contact 11. The arc eliminator 14 is arranged to emit hydrogen from the hydrogen storage metal when the same is heated. The hydrogen storage metal is formed of plural particles of mainly a chemical element, which is arranged so that the generation amount of at least one of metal and metal ion is smaller than a predetermined value, and the ionization tendency of which is equal to or smaller than the ionization tendency of magnesium. |
