PROBLEM TO BE SOLVED: To produce a nanocrystal superconducting wire material in a conformation embedded in a metal or alloy matrix as a stabilizing material. SOLUTION: The method for manufacturing a superconducting wire material made of nanocrystals includes processes of: (1) forming a metal or alloy polycrystalline thin plate as a stabilizing material; (2) forming one or more layers of alloy or oxide nanocrystal buffer layers by an MOCVD method, MBE method, sputtering method, vacuum vapor deposition method, laser ablation method or the like. Further, the method includes processes of: (3) forming a superconducting nanocrystal layer by using heat treatment and a device which can deposit layers while controlling the atomic ratios in the MOCVD method, MBE method, sputtering method, vacuum vapor deposition method, laser ablation method or the like; and (4) if necessary, thinning wires and repeating to deposit layers of buffer layers and superconducting layers; and (5) covering the layers with a metal or alloy coating layer as a stabilizing material.
