A movable contact of a contact device includes a first contact unit and a second contact unit that come into contact with outer surfaces of fixed terminals and a connecting portion connecting the first contact unit and the second contact unit. Here, the first contact unit separates from the outer surface by moving in a direction that is different from a moving direction of a moving body and that intersects an extending direction of a portion that makes contact with the first contact unit of the outer surface. Also, the second contact unit separates from the outer surface by moving in a direction that is different from the moving direction of the moving body and that intersects an extending direction of a portion that makes contact with the second contact unit of the outer surface.
