A low profile transformer includes a first core and a second core respectively having a projection, a first printed circuit board and a second printed circuit board serving as primary windings of the transformer and having a hole for allowing the projections of the cores to penetrate therethrough, respectively, and an insulation wire wound around the projections of the cores as secondary windings of the transformer. The low profile transformer becomes smaller in size and lighter in weight and can meet the isolation safety standard and reduce the manufacturing costs. Furthermore, a variety of cores can be applied to the low profile transformer for a wide range of electrical current loading.
