There is provided an inverter device that is small in size and has high durability against long-term use with vibration. A power substrate 20 is placed at a bottom portion of a box-shaped module case 11, and a control substrate 30 forms a lid of an opening in the module case 11, and thus an inverter device 10 of the present invention is modularized, thereby reducing a height of the inverter device 10. In the inverter device 10, a capacitor 22 is provided between the power substrate 20 and the control substrate 30, and the capacitor 22 is covered with a resin mold layer 12 and fixed in the module case 11. The capacitor 22 is fixed in the module case 11 by the resin mold layer 12, which provides higher durability against vibration than that by conventional fastening with a screw.
