Abstract
A purpose of the present invention is to provide a coated conductor having a high critical current and low AC loss. The high-temperature superconducting coated conductor that achieves this purpose has an elongated first metal substrate, and multiple filaments arranged on the first metal substrate so as to extend in a longitudinal direction of the first metal substrate. The multiple filaments are arranged approximately in parallel with gaps therebetween, and each filament includes, in order from the first metal substrate side, a first superconducting layer containing a rare earth element, first stabilizing layers, second stabilizing layers, and a second superconducting layer containing a rare earth element.
