Abstract
A method of manufacturing a superconducting tape wire, wherein a reduction in critical current in the superconducting tape wire and the effective AC loss are suppressed. To manufacture the superconducting tape wire, the filaments filled with superconducting material powder and having a flat elliptic or rectangular cross section are disposed in a pipe having a shape whose sides in a pressing direction have a smaller length than adjacent sides, and then the pipe is compressed in the short-side direction to form the pipe in a tape shape.
