Title:
【発明の名称】チップ形インダクタおよびその製造方法
Document Type and Number:
Japanese Patent JP3002946
Kind Code:
B2
Abstract:
PURPOSE: To provide a chip type inductor and manufacture thereof having excellent mass productivity and stable and excellent impedance characteristics. CONSTITUTION: A bar body 8 is formed from extrusion molding step using the first primary extrusion molding machine 7 of a kneading material 6 comprising a magnetic body material particles B and coupling material S and after winding a conductor wire 10 around the bar body 8 in a coil shape, said bar body 8 is wound up with the conduction wire 10 using the secondary extrusion molding machine 11 of another kneading material 12 so as to form an exterior body and then the bar body 8 and the exterior body, after baking step are cut off in a specific length to form a plurality of chip type inductor main body 13. Next, the gaps (not shown in figure) formed between the coil conductor wire 10 and the magnetic body is filled up with a specific paste and then external electrodes connecting to the ends of the exposed conductor wire 10 are formed on both end faces of the chip type inductor main body 13.
