An electric compressor includes: a compressing unit; an electric motor that rotates the compressing unit; and a driving circuit driving the electric motor. The driving circuit includes a filter circuit inserted into a power supply line; an inverter circuit that receives electric power from the power supply line via the filter circuit; a circuit board (146) on which the inverter circuit is disposed; and a metal base member (aluminum base (142)) supporting the circuit board (146). The filter circuit has an electromagnetic coil (L1) and a damping resistor (R1). The damping resistor (R1) is fixed to the aluminum base (142) in abutment with the aluminum base (142). Preferably, the filter circuit is mounted on the circuit board (146), and the damping resistor (R1) has a lead line soldered to the circuit board (146) and is fixed to the aluminum base by a screw (172). Accordingly, the electric compressor can be provided which is capable of effectively cooling the damping resistor of the filter circuit. |
