This paper shows that at a certain finite temperature, a Cooper-pair insulator undergoes a transition to a superinsulating state with infinite resistance. Experimental evidence of this transition in titanium nitride films is presented and it is demonstrated that the superinsulating state is dual to the superconducting state: it is destroyed by a sufficiently strong critical magnetic field, and breaks down at some critical voltage which is analogous to the critical current in superconductors.
