Disclosed is a method for producing a superconducting wire material, the method comprising: a first coating step of coating a raw material of superconducting wire material with a first silver-containing metal to obtain a silver sheath member; a non-silver coating step of coating the silver sheath member with a non-silver metal; a compounding step of intermetallically compounding at least a part of the first silver-containing metal in the silver sheath member which has passed through the non-silver coating step with the non-silver metal; an oxidizing step of oxidizing the intermetallically compounded metal to form a high resistivity layer; and a sintering step of heat-treating the member having the high resistivity layer formed thereon to convert the aforementioned raw material to a superconducting material.
