ABSTRACT:
Electronic parts, such as tip inductors may be formed by molding a first molded component as a core by kneading a magnetic material, such as ferrite powder, and a binder, such as resins, spirally winding a conductive material on the periphery of the first molded component with a constant winding pitch, molding a second molded component by covering the periphery of the conductive material as well as the first molded component with a kneaded mixture of a magnetic material, such as ferrite powder, and a binder, such as resins, to form a cover component, integrally sintering both of the first molded component and the cover component, cutting the second molded component into tips of desired length, to thereby partially expose the conductive material out of both end surfaces of the second molded component. Further, terminal electrodes may be fixed to said conductive material at each of the end surfaces of the second molded component where said conductive material of said tips is partially exposed.
