PURPOSE: A manufacturing method of a surface mounting power inductor is provided to prevent the crack inside an inductor by uniformly distributing the pressure inside an inductor. CONSTITUTION: A secondary perform for a top magnetic metal powder layer(A) is formed. A secondary preform for an outer magnetic metal powder layer(B) is formed. A preform for a core magnetic metal powder layer(C) is formed. A coil element(15) is arranged in the neighboring of the preform for a core magnetic metal powder layer. The preform for a core magnetic metal powder layer is arranged in the hollow(Bo) of the preform for an outer magnetic metal powder layer. The preform for a top magnetic metal powder layer is arranged on the preform for a core magnetic metal powder layer.
