A first yoke is arranged in a contact direction with respect to a movable contact piece. A second yoke is arranged in an opening direction with respect to the movable contact piece. The first yoke and the second yoke are configured to generate a magnetic force that attracts the first yoke and the second yoke to each other when the movable contact contacts the fixed contact and is energized. The first yoke and the second yoke are arranged not to contact each other so that the movable contact piece can contact the fixed terminal in a state where the movable contact and the fixed contact are lost.
