PROBLEM TO BE SOLVED: To provide a coil component which does not affect characteristics such as inductance and copper loss even when soft magnetic cores are stacked, and which has excellent heat radiation.SOLUTION: A coil component 100 is composed of at least two toroidal cores 101 and 102 and coil parts 103 and 104. At least one magnetic gap 105, 106 is provided in each toroidal core 101, 102, and a plane part of each toroidal core includes at least one radial groove 107, 108. The depths of the grooves 107, 108 are respectively larger than the diameters of conductors forming the coil parts 103 and 104. |
