<P>PROBLEM TO BE SOLVED: To provide a winding type common mode choke coil wherein bonding strength is ensured between a ferrite component for winding and a ferrite component for forming a closed magnetic path, and the extrusion of an adhesive agent to the outside is prevented without causing an increase in manufacturing cost and the deterioration of performance, and to provide a method for manufacturing the coil. <P>SOLUTION: This winding type common mode choke coil is equipped with the ferrite component for winding. The ferrite component is provided with legs 16a, 16b, 16c and 16d which are formed at corners of a bottom surface side and in which electrodes 13a, 13b, 13c and 13d are arranged on ends, and attaching parts 14a, 14b of the ferrite component 20 for forming a closed magnetic path of which the parts are formed on an upper surface side opposite to the bottom surface side and in which previously set steps DT are formed on side surfaces and around which a winding 11 is wound. <P>COPYRIGHT: (C)2004,JPO |
