PROBLEM TO BE SOLVED: To provide a contact device, which allows an increase in an arc voltage generated between contacts and also enables interruption of a high DC voltage. SOLUTION: A contact device of the present invention includes a fixed contactor 21 having a fixed contact 21C; a moving contactor 22 having a moving contact 22A, the moving contact 22A being moved in such a manner that it is in contact with, or separated from the fixed contact 22C; a container receiving the fixed contact 21C and the moving contact 22A; and a driving portion 1 serving to drive the moving contactor 22 such that the moving contactor 22A in contact with, or separated from the fixed contact 21C. The container 25 is formed of an insulating material capable of generating arc-consolidatable gas, and is disposed in the vicinity of the fixed contact 21C and the moving contact 22A. Also, in the container 25, permanent magnets 23 are disposed into which the fixed contact 21C and the moving contact 22A are inserted opposite to each other.
