PROBLEM TO BE SOLVED: To ensure insulation of a circuit board and peripheral components reliably, while reducing the layout area of the circuit board.SOLUTION: A choke coil device 10 houses two sets of choke coil body 11, 12 in an insulation case 14. In the choke coil body 11, 12, a pair of magnetic cores 22, combining a center leg, a pair of outside legs, and an articulated part, is provided with a winding through a bobbin. Layout area of the choke coil body 11, 12 is reduced by housing the magnetic cores 22, determining the external dimensions, vertically in the insulation case 14, and the insulation case 14 ensures insulation between the circuit board and the peripheral apparatus, when it is arranged on the circuit board. |
