Summary:An arc path formation unit and a direct current relay including same are disclosed. The arc path formation unit according to various embodiments of the present invention comprises a Halbach array and a magnet unit, which form a magnetic field in a space part in which fixed contacts are accommodated. The formed magnetic field forms an electromagnetic force together with the current applied to the direct current relay. The formed electromagnetic force can induce generated arcs Here, the electromagnetic force formed in proximity to the respective fixed contacts is formed in the direction of moving away from the respective fixed contacts. Therefore, the generated arcs do not meet each other, and thus can be effectively extinguished and discharged.
