Zusammenfassung:PROBLEM TO BE SOLVED: To provide a manufacturing method of a low price stable quality magnetic circuit which can prevent the corrosion of the surface of a permanent magnet and reduction of the adhesive strength of a joined part, and has a strong magnetic field. SOLUTION: The present invention is manufacturing of a magnetic circuit, where, in an apparatus including the magnetic circuit with a permanent magnet adhered to a yoke while designed so as to be supplied with a coolant 21, on at least a part contacting to the coolant 21 of the magnetic circuit, a first layer made of at least epoxy resin is spray-coated and then a second layer made of fluoro-resin is spray-coated.
