1. An inverter-integrated electric compressor including an inverter device which has a switching element and applies a three-phase AC output to a motor, comprising:
a control board configured to control switching of the switching element; and
a wiring member provided to establish wiring of a DC power supply, the control board, the switching element, and the motor,
wherein elements for noise reduction are arranged in the wiring member, and
wherein the elements for noise reduction include at least reflux capacitors to reflux an outflowing common mode current to a noise source in a short reflux path.
