<p>Provided is a low-cost compressor having excellent operation stability which enables the improvement of the stability of a control circuit by shielding electromagnetic noise and the effective prevention of the vibration of a control substrate while the design flexibility is maintained at the same high level as that of conventional ones. An inverter-integrated electric compressor in which a motor is embedded and a motor driving high-voltage circuit including an inverter and a control substrate provided with a controlling low-voltage circuit are provided in a compressor housing is characterized in that a shield plate produced from a material capable of shielding electromagnetic noise emitted from the motor driving high-voltage circuit toward the controlling low-voltage circuit is disposed between the motor driving high-voltage circuit and the control substrate, and the shield plate and the control substrate are fixed to each other and both are fixed at a predetermined position in the compressor housing.</p>
