A method of manufacturing a transformer is disclosed. First, a first bobbin piece is provided, wherein the first bobbin piece has a first channel therein and a primary winding section. Second, a second bobbin is provided, wherein the second bobbin piece comprises a first secondary side plate, a second secondary side plate opposed to the first secondary side plate, a plurality of partition plates between the first secondary side plate and the second secondary side plate, a wall portion between every two adjacent partition plates, and a secondary base extended from an edge of the first secondary side plate and having a first pin arranged on a bottom surface of the secondary base, wherein a plurality of secondary winding sections are defined by every two adjacent partition plates, and a second channel is defined within the wall portion. Then a second pin is inserted into the second bobbin piece to penetrate through the wall portion and the second secondary side plate and form a wire-arranging part protruded from the second secondary side plate and an insertion part protruded from the bottom surface of the secondary base. Later, a primary winding coil is wound on the primary winding section, a first terminal of a secondary winding coil is fixed on the first pin and then wound on the secondary winding sections, and a second terminal of the secondary winding coil is fixed on the wire-arranging part of the second pin. Finally, a magnetic core assembly is partially disposed within the first channel of the first bobbin piece and the second channel of the second bobbin piece.
