A frequency converter in which the inductance is reduced by enlarging the forms of bus bars which connect a P phase, an N phase of an inverter part and a positive electrode or a negative electrode of smoothing capacitors and the form of a wiring bus bar which connects an intermediate layer of capacitors which are connected in series to enlarge areas where they overlap each other, and by making currents flow in the opposite directions to each other.
