摘要： The invention provides an oxide superconductor capable of sufficiently withstanding external forces such as a large electromagnetic force and thermal stresses accompanying rapid heating and cooling while in service, and internal stresses so as to be able to exhibit a high trapped magnetic field stably over a long period of time. The oxide superconductor such as, for example, “a copper oxide superconductor containing rare earth elements”, is composed of an oxide superconductive bulk body impregnated with a low melting metal or an oxide superconductive bulk body impregnated with a low melting metal and having a thin film of the low melting metal formed on the external surface thereof. Such oxide superconductors as described above can be produced by a process whereby the oxide superconductive bulk body kept in an atmosphere of reduced pressure is brought into contact with the low melting metal. Further, if the oxide superconductive bulk body is provided with pores beforehand, so that contact faces thereof with the low melting metal in a molten state are both the external surface of the oxide superconductive bulk body and the inner surface of the respective pores, further improvements in production efficiency and product performance can be expected.
