PURPOSE:To obtain the superconducting coil having high stability by applying synthetic resin adhesives onto one surface of an organic synthetic film, winding the applied surface on the outside of a wire rod, winding the wire rod on a coil form in line and heating and pressing the wire rod. CONSTITUTION:A tape obtained by prepreg-treating only one surface of the organic synthetic film made of polyester, etc. by a material under a B stage condition by resin such as thermocuring resin or the synthetic resin adhesives of thermoplastic resin is wound on the outer circumference of a superconducting straight angle formed stranded cable, a superconducting straight angle cable, etc. while directing the applied layer outwards. When the form of the coil is kept by adhesive force only between the insulating tape when molding the coil and the coil is incorporated into a magnet structure, such as an iron core or a stainless collar or the like, the quantity of shrinkage is predicted previously through cooling, the coil is cooled and the coil is incorporated into the magnet structure through heating and pressing. Accordingly, the superconducting coil having high stability can be obtained.
