Abstract
An embedded inductor suitable for a wiring board is provided. The wiring board having a plurality of patterned conductive layers and a plurality of insulating layers, and one of the insulating layers is disposed between any two adjacent of the patterned conductive layers. The embedded inductor at least includes a first conductive trace, a second conductive trace, a third conductive trace, a first conductive structure, and a second conductive structure. These conductive traces are respectively formed of different patterned conductive layers of the wiring board. The first conductive structure and the second conductive structure passing through the insulating layers connect the conductive traces in a spiral pattern. The embedded inductor with such spiral pattern is arranged on a plane that is perpendicular to the patterned conductive layers of the wiring board.
