Summary: 
The size of the true contact area of electrical contacts at very low temperature was evaluated by the breakdown of the superconduction caused by the self magnetic field of the current. Qutline of the breakdown of the superconduction in the true contact area were qualitatively clarified by the appearance of the constriction resistance.
