The hollow tubular capacitor includes one side electrode connecting portion having an inner peripheral tubular portion and a one side surface portion, the other side electrode connecting portion having an outer peripheral tubular portion and the other side surface portion and an electrostatic capacitance portion having one side electrode plate, the other side electrode plate and a dielectric body , wherein the electrostatic capacitance portion is accommodated in an annular space formed at the inner peripheral tubular portion, the one side surface portion, the outer peripheral tubular portion and the other side surface portion in a high density to reduce inside inductance component. The inverter device according to the invention is formed such that the hollow tubular capacitor and an annular inverter circuit portion having three-phase upper and lower arms are integrally arranged coaxially on the central axis line. The inverter device is formed such that the one side electrode connecting portion and the other side electrode connecting portion and the three-phase upper and lower arms are electrically connected to each other to prevent generation of surge voltage and transferring thereof and at the same time achieve reduction of size and weight. |
