Abstract
An electronic device comprising a first magnetic powder, a second magnetic powder and a conducting wire buried in the mixture of the first magnetic powder and the second magnetic powder is provided. The conducting wire comprises an insulating encapsulant and a conducting metal encapsulated by the insulating encapsulant. The Vicker's Hardness of the first magnetic powder is greater than the Vicker's Hardness of the second magnetic powder, and the mean particle diameter of the first magnetic powder is larger than the mean particle diameter of the second magnetic powder. By means of the hardness difference of the first magnetic powder and the second magnetic powder, the mixture of the first magnetic powder and the second magnetic powder and the conducting wire buried therein are combined to form an integral magnetic body at the temperature lower than the melting point of the insulating encapsulant.
