A polygonal mirror comprising a mirror body in the form of a regular prism. A plurality of side faces of the regular prism are formed respectively into reflecting faces. During rotation of the mirror body about its central axis, the reflecting faces successively deflect an indicent light ray to cause the deflected light ray to carry out scanning. A flange is integrally provided on the mirror body, and has a size at least equal to a circle circumscribing the regular prism in a plane perpendicular to the central axis.
