Characteristics of superconducting point contact junctions are investigated both theoretically and experimentally. The dependence of the maximum zero-voltage current on contact pressure is measured with Nb-Nb superconducting point contact junctions. The experimental results are qualitatively consistent with those theories which were recently presented by several authors. There are also observed the characteristics which are not satisfactorily explained yet. The usefulness of the superconducting point contact junction as a far-infrared detector is examined theoretically for the future experiment.
