PROBLEM TO BE SOLVED: To provide an inverter device 1 that prevents the occurrence of an eddy current (an induction current) due to a current flowing through a coil and prevents a reduction in an inductance value of a choke coil.SOLUTION: In an inverter device 1 including a substrate 11 on which a capacitor 16 and a semiconductor element 17 and the like are mounted; a metal housing 10 for fixing the substrate 11; and a choke coil 2 having an open magnetic path structure, having a rod-shaped core 15 disposed perpendicular to the substrate 11, and electrically connected to the substrate 11 via coil terminals 14a and 14b of the coil 14, one or more notches 30 are provided on a surface of the substrate 11 facing an end portion (a lower end portion) in an axial direction of the rod-shaped core 15 of the choke coil 2. |
