A relay includes a first fixed contact, a second fixed contact, a movable contact piece having first and second movable contacts, a contact piece holding unit configured to hold the movable contact piece, and first to fourth magnets. The first magnet and the second magnet are disposed so that same poles thereof face each other. The movable contact piece is disposed between the first magnet and the second magnet in a width direction of the movable contact piece. The third magnet is disposed so as to increase a magnetic flux in a longitudinal direction of the movable contact piece at a position between the first fixed contact and the first movable contact. The fourth magnet is disposed so as to increase a magnetic flux in the longitudinal direction of the movable contact piece at a position between the second fixed contact and the second movable contact.
