Abstract
There is provided an integrated electric compressor that can be made small in size while reducing radio noise effectively. In an inverter of the electric compressor, a snubber circuitcomprising a resistor R and a capacitor C is provided between input/output terminalsof a power source and a switching element. The snubber circuitis formed by surface mounting a resistive element constituting the resistor R and a capacitor element constituting the capacitor C on a power board. A leakage current from a motoris thus restrained and radio noise is reduced. The resistive element and the capacitor element constituting the snubber circuitare preferably surface mounted on the power boardon the side opposite to the side on which a control circuit board is arranged.
