Abstract: A magnetic component is configured to be used with a coil wound about a center axis along an axis direction. A first magnetic member is configured such that magnetic flux generated by the coil passes therethrough, extends in the axis direction to have first and second ends, and has a portion overlapping with the coil viewed perpendicular to the axis direction. A second magnetic member is disposed on an opposite side to the coil with respect to the first end of the first magnetic member, in the axis direction. A third magnetic member is disposed on an opposite side to the coil with respect to the second magnetic member, in the axis direction. The third magnetic member is larger in magnetic anisotropy than each of the first magnetic member and the second magnetic member, and has an easy direction of magnetization oriented perpendicular to the axis direction.
