PROBLEM TO BE SOLVED: To provide a DC relay capable of stably performing the cut-off of a DC high voltage. SOLUTION: The DC relay comprises a pair of contacts having contacts 2, 3 mutually opening and closing, a contact housing case 1 for housing the pair of contacts, and a drive 5 for opening and closing to drive one contact. The drive 5 and the contact housing case 1 are fixed by screwing in opening and closing directions of the contacts. By a configuration that drive and the contact housing case are fixed by screwing in the opening and closing directions of the contacts, the movable direction of the driven shaft of the drive and the direction of the screwing become the same direction, and then the contact housing case does not shift to the drive even by reusing the relay. Consequently, dispersion in a distance between the contacts can be suppressed, the stable contact state of the contacts can be maintained, and then the contacts can be securely brought into a noncontact state.
