A transformer includes a main body and a wire. The main body has several winding partitions and two end portions. Several leads are disposed in either end portion and a buffer region is formed between the right end portion and the right-most winding partition. An intermediate area is disposed between the buffer region and the right-most winding partition. One end of the wire is connected to one of the leads and the wire passes the right end portion. Before the wire goes into the buffer region, the wire is folded for several times and then is twisted and rolled for several turns to make the wire thicker. Next, the thicker wire is wound around the iron core in the buffer region for several turns and then the thicker wire passes the intermediate area and goes into the right-most winding partition.
