Claim:
1. A method for manufacturing an MgB 2 superconductor comprising: (I) adding a polycyclic aromatic hydrocarbon to a B powder, while heating to a temperature higher than or equal to the melting point of the polycyclic aromatic hydrocarbon at the time of this addition, and thereby covering a surface of the B powder with the polycyclic aromatic hydrocarbon; (IIa) mixing the B powder having the surface covered with the polycyclic aromatic hydrocarbon, with an Mg powder or an MgH (IIb) packing a metal tube with the B powder covered with the polycyclic aromatic hydrocarbon and an Mg rod; and (III) pressure molding and heat-treating the packed metal tube, thereby producing the MgB
