A coil component has a core part 10 composing a closed magnetic path through which a closed loop of a magnetic flux passes, the magnetic flux being generated by two coils 14A, 14B that are arranged in parallel, and generate a magnetic field, and the core part 10 has a pair of I-type base cores 11A, 11B facing each other, and a pair of coupling core parts 11C, 11D. The coupling core parts 11C, 11D are each formed by linearly aligning three unit coupling cores 12A to 12F, and each of these cores 12A to 12F is formed into a configuration in which a column-shaped projection is provided on a core body, and a two-stage gap including a small gap and a large gap is to be formed mutually in a space in the adjacent unit cores 11A, 11B, and 12A to 12F by the configuration. |

1. A coil component comprising a coil and a core part composing a closed magnetic path through which a closed loop of a magnetic flux generated by the coil passes, wherein
the coil component is configured in such a manner that the core part is formed of a plurality of unit cores, the plurality of unit cores are magnetically and sequentially coupled, and the closed magnetic path is formed as a whole, and a gap is formed by being provided between at least one set of the magnetically coupled adjacent unit cores, and a projection is provided on an end surface of at least one of the adjacent two unit cores with interposing the gap therebetween, and the gap is formed of at least two types of gaps including a small gap and a large gap. |
