Abstract
An embedded transformer embedded in a board is disclosed. The embedded transformer includes a board, a first insulating sheet, a preformed coil, a second insulating sheet, a first core and a second core. Among these, the board includes a conductive pattern formed on an upper surface of the board. A part of said conductive pattern serves as a primary coil of the embedded transformer. The first insulating sheet is formed on the conductive pattern. The preformed coil is formed on the first insulating sheet. The second insulating sheet is formed on the preformed coil. The first core is formed on the second insulating sheet and partially embedded in the board. The second core formed on a lower surface of the board is partially embedded in the board so as to be couple to the first core.
