The present invention relates to an MgB-based superconductor that is easy to manufacture and well suited to mass production, and that exhibits excellent superconducting characteristics (such as a high critical current density) while still retaining the high critical temperature characteristics of MgB. A powder mixture of magnesium, boron, and titanium is pressed into a pellet, and this product is sintered under an atmospheric pressure and other conditions (preferably at 600&#xb0; C. or higher) to manufacture an MgB-based superconductor in which titanium and/or a titanium compound are dispersed in polycrystalline MgB.

There is provided a power lead for a superconductive magnet capable of controlling the invasion of heat to liquid helium for storing superconductive coils therein and of sufficiently feeding power to the superconductive coils. The power lead for a superconductive magnet of a superconductor magneto unit for supplying a current to the superconductive coils which are cooled at a liquid helium temperature through a radiant heat shielded section which is cooled at a liquid nitrogen temperature, wherein at least a part of sections positioned inside the radiant heat shielded section of a current lead member of the superconductive magnet comprises a high temperature oxide superconductor bulk body having a critical temperature exceeding a liquid nitrogen temperature. In this case, it is preferable to apply a resin impregnation treatment to the bulk body to enforce the high temperature oxide superconductor bulk body section. If at least a part of sections other than the bulk body is formed of a braided wire, a stress caused by the relative displacement between constituents of the unit does not influence upon the bulk body, thereby reducing the risk of breakage of the unit.
