<p>Disclosed is a low AC-loss multi-filament type superconductive wire material comprising a lengthy base material, an intermediate layer formed upon this base material, a superconductive layer formed upon this intermediate layer, and a metal stabilizing layer formed upon this superconductive layer. A plurality of slots, running along the longitudinal direction of the aforementioned base material, extending to the aforementioned intermediate layer from the aforementioned metal stabilizing layer via the aforementioned superconductive layer, and exposing the aforementioned intermediate layer, are formed in parallel in the width direction of the aforementioned base material, and the difference (dd = d1 - d2) between the width (d1) of the aforementioned slots at the lower part of the aforementioned superconductive layer, and the width (d2) of the slots at the lower part of the aforementioned metal stabilizing layer is not more than 10 µm.</p> |
