Abstract: A magnetic component includes a first core, a second core, an outer bobbin, a first winding, an inner bobbin and a second winding. The outer bobbin is disposed between the first core and the second core. The outer bobbin has a hollow tube portion, a first bottom portion and a first top portion. The first winding is wound around outer side of the hollow tube portion. The inner bobbin is disposed in the hollow tube portion. The inner bobbin has a second bottom portion and a second top portion. The second winding is wound around the inner bobbin. The second bottom portion is exposed to bottom side of the first bottom portion, such that the first bottom portion overlaps the second bottom portion in a height direction of the magnetic component. The second top portion and the second bottom portion abut against inner side of the hollow tube portion.
