A superconductive wire conductor is produced by: embedding a plurality of deposition substrates formed to have a predetermined size in parallel with each other to a connection base material to connect and integrate therewith; depositing an intermediate layer, a superconductive layer and a protective layer on a deposition surface side of the deposition substrate; and winding a single or multiple integrated superconductive conductors around a desired core material, separating each single superconductive wire from the integrated superconductive conductor and winding each superconductive wire around the core material or winding the integrated or separated wire alternately, whereby a superconductive conductor having a good superconductive characteristic without a problem regarding a shape thereof such as local protrusions.
