Claim:
1. A magnetic component comprising: a first winding; and a second winding which is insulated from the first winding and magnetically couples with the first winding, wherein the first winding forms a first coil unit by being wound, the second winding forms a second coil unit by being wound about a same axis as the first winding, the second winding forming the second coil unit is disposed in an area X and an area Z, where the area X is an area, in an axial direction, in which the first coil unit is not disposed, and the area Z is an area, in the axial direction, in which the first coil unit is disposed, and the first coil unit and the second coil unit are disposed at positons that satisfy following Equations 1 and 3: where r1min is a distance between an innermost periphery of the first coil unit and the axis, r1max is a distance between an outermost periphery of the first coil unit and the axis, rX is a distance between the innermost periphery of the second coil unit and the axis in the area X, and rZ is a distance between the innermost periphery of the second coil unit and the axis in the area Z.
