PROBLEM TO BE SOLVED: To provide a magnetic device capable of suppressing flux saturation even when magnetic fluxes concentrate at a curved portion or an edge portion in contact with a gap, existing in a magnetic core forming the magnetic device, such as a reactor or a transformer.SOLUTION: In the magnetic device 3 having a toroidal magnetic core and a coil 4 wound around the magnetic core, the magnetic core is formed from a material with saturation flux density of a magnetic flux concentration portion where magnetic fluxes concentrate higher than those of portions except the magnetic flux concentration portion. |
