<p>A method of processing width of a superconducting wire rod is provided, in which slit processing is performed to a superconducting wire rod formed using a wide substrate, without deteriorating the superconducting feature and at high production efficiency. The method includes a step of preparing the superconducting wire rod S and a step of cutting the superconducting wire rod S by processing portions (31-35) each having two opposing cutting portions (21-30). At least two sets of the processing portions (31-35) are arranged adjacent to each other with a distance in a width direction of the superconducting wire rod S so that the superconducting wire rod S is interposed between the two cutting portions (21-30). Contacting positions of the cutting portions (23, 26, 27, 30) contacting one surface (S2) of the superconducting wire rod (S) are externally positioned in the width direction of the superconducting wire rod (S) relative to contacting positions of the cutting portions (24, 25, 28, 29) contacting the other surface (S1) of the superconducting wire rod (S).</p> |
