Abstract
A tubular metal pipe and a solidified melt of a precursor of oxide superconducting material which is placed in contact with the metal pipe are subjected to heat treatment in an oxidizing atmosphere and at a temperature above the partial fusion temperature of the solidified melt to oxidize the metal pipe from its inside and outside and, as the oxidation proceeds, a melt of the solidified melt is effused through the tubular metal oxide layer to form a superconducting layer on its surface. This makes it possible to easily obtain a hollow oxide superconductor wherein a superconducting material layer is formed outside the metal oxide layer.
