A coil for a magnetic resonance device is provided. The coil includes a cylindrical coil insulating frame with at least one winding groove running around its circumference, at least one coil conductor wound into the winding groove around the coil insulating frame, and one electrically-insulating insulator lining the winding groove and insulating the coil insulating frame and the coil conductor from each other. The insulation includes a number of molded insulating segments that line the winding groove, supplementing each other to form a circular ring which matches the cross-sectional shape of the winding groove.
