An electric compressor includes a compression mechanism, an electric motor for driving the compression mechanism, and a drive circuit for controlling the electric motor. The drive circuit includes an external connector made of an insulating material. The external connector has a connecting terminal that is constructed to be electrically connected to an external power source. The drive circuit further includes a circuit board electrically connected to the connecting terminal and a filter element electrically connected to the circuit board. The drive circuit is accommodated in a metal housing. The filter element is integrally formed with the external connector such that contact of the filter element with the housing is prevented.
