PROBLEM TO BE SOLVED: To provide an oxide superconducting wire having little deterioration in critical current density with respect to bending of the oxide superconducting wire and its manufacturing method. SOLUTION: In a multi-filament type oxide superconducting wire, 18 oxide superconducting conductors 1 with round cross sections are divided and disposed in two layers in a sheathing material 2. While each superconducting conductor 1 is disposed spirally to the center of the oxide superconducting wire 3 with a round cross section through a twisting process, the center part is filled with the sheathing material. The ratio of the distance a between an almost center of the superconducting conductor 1 positioned at an outermost layer and the center of the superconducting wire 3 to a spiral pitch P, which is not shown in the figure, is set so as to be within a designated range.
