PROBLEM TO BE SOLVED: To obtain a parallelized superconductor that can suppress AC loss, cope with a coil having a small radius of curvature, and is easily manufactured, and to prevent the burning, or the like of a conductor due to an overcurrent in the facilitation of an increase in current capacity, excitation inrush, sudden short-circuiting accidents, or the like as a superconducting coil. SOLUTION: In the superconductor, a plurality of oxide superconducting wires 20a, covered with an electrically insulating material or a high-resistance material, are arranged in parallel in the direction of a conductor width. The superconducting coil is set to be a secondary parallel conductor, where the superconductor is wound in a single layer or a plurality of layers individually, or a plurality of superconductors are arranged in parallel in the direction of a coil axis. The secondary parallel conductor is wound in a single layer or a plurality of layers, and a part, where vertical flux linkage acting between respective oxide superconducting wires of the superconductor acts so that the vertical flux linkage is canceled each other by the distribution of a magnetic field generated by the superconducting coil, is provided at least partially in terms of the structure and arrangement of the superconducting coil.
