Disclosed is a method oft by using a plastic molding process, encapsulating an air-core coil with a moldable magnetic resin material prepared by kneading a mixture of a magnetic powder and a resin. The method comprises the steps of (a) preparing a molding die assembly which includes a plurality of dies adapted to define a cavity therewithin, and a positioning pin adapted to be movable in a vertical or horizontal direction within the cavity, (b) arranging the air-core coil at a given position within the cavity by the positioning pin, (c) charging the moldable magnetic resin material into the cavity and moving the positioning pin to a given retracted position in a course of the charging.
