A contact mechanism includes a first fixed contact, a second fixed contact, a first movable contact that faces the first fixed contact, and that is disposed so as to come into contact with or be separated from the first fixed contact, and a second movable contact that faces the second fixed contact, and that is disposed so as to come into contact with or be separated from the second fixed contact. The first fixed contact and the first movable contact are disposed so as to face each other in a direction intersecting with a contact-separation direction in which the first movable contact and the second movable contact come into contact with or are separated from the first fixed contact and the second fixed contact. The second fixed contact and the second movable contact are disposed so as to face each other in the direction intersecting with the contact-separation direction.
