PROBLEM TO BE SOLVED: To provide a cylindrical magnetic field coil which is simply formed without generating warps at coils 20a, 20b, in the cylindrical magnetic field coil formed by making round coils 20, 21 which are connected in parallel with each other by a crossover. SOLUTION: Two pieces of the coils 20a, 20b wound in prescribed winding directions are prepared, leader terminals 31 of the coils which are free ends are joined by connecting conductors 4 each having a shape not larger than a quarter, preferably one fifth of a section coefficient of a flat type conductor 1 which forms the coil, other free ends which are dead end terminals 32a, 32b constitute the magnetic field coil 2 in which two pieces of the connected coil 20 formed into a prescribed shape and the connected coil 21 paired with the other coil, wound in a direction reverse to that of the other coil, and having the same constitution as that of the other coil are formed, and then the cylindrical magnetic field coil is formed by bending recessed faces of the coils 20a, 20b so as to be round which are partially bent and processed into circumferential shapes in advance, into the inside of the magnetic field coil.
