A plurality of windings in a coil winding of a superconducting coil device includes at least one superconducting strip conductor that has a strip-shaped substrate strip and a superconducting layer arranged on the substrate strip. The coil device is subdivided into a plurality of segments in which adjacent windings are cast or adhered together within each segment, adjacent windings being, at most, weakly connected or adhered together in at least one sub-region, in the intermediate region between two adjacent segments.
