Abstract
An oxide superconducting wire includes a superconducting layer deposited on a substrate. The superconducting layer includes an oxide superconductor RE-Ba—Cu—O and artificial pinning centers ABO, where RE is a rare earth element, A is Ba, Sr or Ca, and B is Hf, Zr, or Sn. In a TEM image of a cross-section of the superconducting layer, a standard deviation σ of an inclination angle of the artificial pinning center rods with respect to a cross-sectional direction of the superconducting layer is 6.13° to 11.73° and an average length of the artificial pinning center rods is 19.84 to 25.44 nm.
