| 1. An integrated type transformer comprising:
a bobbin unit including a bobbin body having a predetermined length and a through hole therein in a longitudinal direction
of the bobbin unit;
a core unit including an inner core inserted into the through hole of the bobbin unit, and an outer core positioned outside
the bobbin unit and formed along one surface of the bobbin unit in the longitudinal direction thereof and electromagnetically
coupled to the inner core to form a single magnetic path;
a coil unit including a primary coil wound around the outer circumferential surfaces of the bobbin unit and a plurality of
secondary coils electromagnetically coupled to the primary coil; and
a terminal unit including plurality of input terminals transmitting input power to the primary coil and plurality of output
terminals transmitting output power from the secondary coils;
wherein the output terminals of the terminal unit are arranged at the one surface of the bobbin unit along a longitudinal
direction of the bobbin unit, the output terminals being adjacent to the outer core and configured to form an electromagnetic
reaction with the outer core; and
wherein the input terminals of the terminal unit are formed at another surface opposite to the one surface of the bobbin unit.
