Intermittent superconductivity for mesoscopic thin-film rings is investigated by the phenomenological Ginzburg-Landau theory. Phase diagram for intermittent superconductivity vs. ring dimension is given in the presence of an external applied field. The intermittent superconductivity exists only in the small ring, which is a feature for distingushing superconductive ring from superconductive disk.
