<P>PROBLEM TO BE SOLVED: To provide a coil component, a reactor, and a method for forming the coil component, which enable easy processing for forming multiple coil elements, arranged parallel to each other, by a flat wire. <P>SOLUTION: In the coil component 20, two coil elements 21 and 22 are formed in a rectangular cylinder shape by winding a flat wire 30 edgewise. The two coil elements 21 and 22 are arranged parallel to each other, and the winding direction of each coil element is the same. A contact portion 40 of the flat wire 30 interposed between the coil elements 21 and 22, which are arranged continuously, is protruded by winding the flat wire 30 edgewise so that part of the contact portion 40 protrudes toward an outer diameter side relative to the two coil elements 21 and 22. Further, the contact portion 40 is wound flatwise at three positions including a folding portion, thereby arranging the coil elements 21 and 22 in parallel so that axis lines of the two coil elements 21 and 22 are parallel to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
