PURPOSE:To simplify manufacture and lower the cost by forming a helical conductive film on the surface of magnetic core in place of a winding wound in several layers. CONSTITUTION:A conductive film 2 of metal is deposited on the surface magnetic core 1 by the method such as plating and a helical conductive film 2' is formed by giving a helical cut-away groove 3 to said conductive film 2. The groove 3 is formed using a spiral cutter for manufacturing a resistor. The terminal or electrode 4 is formed by executing a thick plating to both ends with the solder. An insulating protection film 5 such as a paint is deposited on the helical conductive film 2' and it is used as a chip inductor. Here, it is no longer necessary to form a spool type cylindrical magnetic core and form a winding. |
