Abstract
A high temperature oxide superconducting wire is provided which is capable of preventing metal located on the outer periphery of the superconducting wire from diffusing into a superconductor to achieve restriction of reduction in the critical current density. The high temperature oxide superconducting wire includes a high temperature oxide superconductor,a sheathing body,formed of material containing silver for coating the high temperature oxide superconductor,, a heat-resistant oxide ceramic material,for coating the sheathing body,, and a coating body,mwhich is inactive relative to the heat-resistant oxide ceramic material,in a high temperature oxidative atmosphere.
