<p>PROBLEM TO BE SOLVED: To reduce the manhours for integrating magnetic parts into a space and make them integrable into a narrow space by providing coils for a plurality of magnetic parts on a nearly single plane, and by integrating the coils for the respective magnetic parts with each other via a ferromagnetic body forming a core, and furthermore, by forming the plurality of magnetic parts out of the core and the coils for the respective magnetic parts. SOLUTION: In a state of providing coils 1 for a plurality of magnetic parts which are substantially flush with each other face, the coils 1 for the plurality of magnetic parts are integrated with each other via a ferromagnetic body 7 forming a core 2. Then, forming a transformer T out of the core 2 and a coil 1a for the transformer T, forming a noise filter F out of the core 2 and a coil 1b for the noise filter F, and forming an inductor I out of the core 2 and a coil 1c for the inductor I, respective magnetic parts 6 are formed. Also, there are provided non-magnetic body portions in the places of the ferromagnetic body 7 forming the core 2 which are interposed between the respective coils 1a, 1b, 1c for the respective magnetic parts 6.</p> |
