PURPOSE:To obtain superconductive wire having a high current density by smoothing the cooling surface, which is facing approximately downward, of the cooling surfaces of a winding portion, providing convex and concave portions at least on the one cooling surface of the other cooling surfaces, and effectively increasing the thermal stream. CONSTITUTION:The cooling surface, which is facing approximately downward, of the cooling surfaces of the winding portions of a coil conductor 1 is smoothed. The convex and concave portions are provided at least on a cooling surface 5 of the other cooling surfaces. By this method, the thermal stream at the coil winding portion can be effectively increased and the superconductive wire having a high current density can be obtained. |
