A relay includes a pair of fixed terminals arranged to respectively have fixed contacts, a movable contact member arranged to have a pair of movable contacts, a driving structure operated to move the movable contact member and a magnet arranged to extinguish an arc. The movable contact member has a center section located between the pair of movable contacts. The magnet is placed on at least one of a first side and a second side that face each other across a predetermined face including the movable contact member and the pair of fixed terminals electrically connected by the movable contact member. The magnet is arranged to have a magnitude relation that a center area where the center section is located has a lower magnetic flux density than movable contact portions where the pair of movable contacts are located.
