Abstract: An inductor includes a first core, a conducting wire, a second core and a first lead frame. There is an accommodating space formed on a first side of the first core and there is a recess portion formed on a second side of the first core, wherein the first side is opposite to the second side. The first core has a first height. The conducting wire is disposed in the accommodating space. The second core is disposed on the first side of the first core and covers the accommodating space. The first lead frame has an embedded portion embedded in the recess portion. The embedded portion has a second height. After embedding the embedded portion in the recess portion of the first core, a total height of the embedded portion and the first core is smaller than the sum of the first height and the second height.
