A section of the wire is in a circular or substantially circular shape. The wire exhibits a critical current density of at least 2000 A/cm2 at a temperature of 77 K with no application of a magnetic field. It is preferable that the plurality of filaments are substantially rotation-symmetrically arranged with respect to the center of the wire. It is also preferable that a hexagonal-prismatic stabilizing matrix is provided at the center of the wire and the plurality of filaments covered with the stabilizer matrix are arranged on each side surface thereof in a layered manner.

摘要： An oxide superconducting stranded wire having inter-strand insulation and high critical current is provided. A wire including an oxide superconducting material and a matrix covering the material and consisting essentially of silver or a silver alloy is coated with a paint containing, as a main component, an organometallic polymer such as a silicone polymer or aluminum primary phosphorus in a paint reservoir, and the paint is baked in a baking furnace via a drying furnace. A plurality of such wires with the baked paint are twined into a stranded wire, which is then heated up to a temperature necessary for sintering the oxide superconducting material. The stranded wire thus obtained through the step of sintering may have high critical current. A heat-resisting insulating coating layer may be formed by baking the paint.
