Summary:PROBLEM TO BE SOLVED: To provide a manufacturing method of a long superconducting wire and band wherein MgB2 is used as the base and wherein high current density can be loaded. SOLUTION: In the case the superconducting wire and band are manufactured by using such an in-tube powder technology that a composite material composed of a shell tube made of superconducting material and superconducting compound or powder of a precursor of this compound contained in the tube are worked into the superconducting wire or band through deformation and heat-treatment, the composite material containing the pulverulent superconducting MgB2 - compound or a pulverulent precursor of the superconducting MgB2 -compound in the shell tube is presented for working, and at this time, the pulverulent precursor is contained in the shell tube as a mechanically alloyed powder partly reacted only to the MgB2 -compound or as a pulverulent mixture compound of a single component of the desired MgB2 -compound.
