Manufacturing method of magnetic component

The invention provides a manufacturing method of a magnetic component. A first plate and more than one convex seat of a first substrate are integrally formed by die processing, the more than one convex seat is processed to form a conductor, a second plate of a second substrate is integrally formed by another one die, a plurality of conductive connection points are processed and formed on a surfaceof one side of the second plate, more than one magnetic conduction inner core is also integrally formed by a third die and is assembled at the more than one convex seat of the first plate, the more than one convex seat is arranged in a plurality of positioning groove holes in a penetrating way, the second plate of the second substrate is assembled at outer sides of the more than one seat and morethan one magnetic conduction inner core, the plurality of conductive connection points are respectively and electrically connected with a plurality of conductors of the more than one convex seat so as to form a magnetic compo
