PROBLEM TO BE SOLVED: To improve reliability of a high-temperature superconducting device so that no connection peels off in a room temperature or in a low-temperature environment, and no degradation in soldering strength at an electrode occurs when a high-temperature superconducting film is connected to the electrode, related to the high-temperature superconducting device. SOLUTION: In the interface between a high-temperature superconducting film 12A and an electrode 13, a titanium compound 20 is inserted such as a valium titanate, for example, generated through heating reaction with a titanium constituting a part of the electrode 13 and the component material of the high- temperature superconducting film 12A.
