The invention relates to the technical field of inductors, in particular to an integrated small-size power inductor and a manufacturing method thereof.The integrated small-size power inductor comprises an inductor body, the inductor body is composed of a soft magnetic substrate, a soft magnetic core, an external magnet and external electrodes, the soft magnetic substrate is internally provided with four electrodes, and the four electrodes are electrically connected through internal conductors; the soft magnetic core is composed of two metalized end end electrodes, a winding portion and an enameled wire coil, the enameled wire coil is wound outside the winding portion, and the two metalized end end electrodes are arranged at the two ends of the winding portion respectively. According to the invention, the integrated batch production of the small-size power inductor is realized through the lamination process, the winding process and the assembly and encapsulation process. The integrated small-size power inducto
