Abstract: A manufacturing method of an integrally formed inductor, comprises: sintering a soft magnetic material to prepare a magnetic core plate with a plurality of grooves; respectively putting hollow coils into the plurality of grooves; putting a magnetic core plate provided with coils into a forming die, adding a soft magnetic material in a fluid state, and integrally forming the soft magnetic material in the fluid state on the magnetic core plate through pressing; coating semi-finished inductors with an insulating material to form an insulating coating layer, and exposing only two terminals of the coils; areas where the coil terminals are exposed on a surface of the insulating coating layer being metallized to form electrodes of the integrally formed inductor. Therefore, the disclosure provides a manufacturing method of an integrally formed inductor which is subminiature in size, ultra-thin and high in reliability.
