Abstract: The present disclosure provides a magnetic component including a winding, a first magnetic core and a circuit component, and a wireless power-transferring device including the magnetic component. The winding is formed by winding a coil, and having a first penetration portion at a middle portion of the winding. The first magnetic core is disposed at a side of the winding, and a first insulating support portion is disposed between the first magnetic core and the winding. The circuit component is located within the first penetration portion and electrically connected with the winding. Disposing the circuit component within the first penetration portion at the middle portion of the winding can effectively save space.
