A superconductive device having a tunneling Josephson element comprises a first oxide superconductor electrode, a blocking layer formed on the surface of the first oxide superconductor electrode by coating a metal substantially inert to oxygen, and an insulating thin film layer formed on the blocking layer, and a second superconductor electrode is coated on the insulating thin film. A method of manufacturing a superconducting device comprises the steps of forming a blocking layer by polishing the surface of an oxide superconductor electrode to a mirror surface, coating a metal substantially inert to oxygen selected from the group consisting of Au, Pt, Ag and Cu onto said substrate, forming an insulating thin film selected from the group consisting of oxide, fluoride and semiconductor on the surface of the blocking layer, and forming a second superconductor electrode on the surface of the insulating thin film, thereby constructing a tunneling Josephson element between the first oxide superconductor electrode and the second superconductor electrode. |
