Inverter-integrated electric compressor

Disclosed is a low-cost, inverter-integrated electric compressor with which a high degree of design freedom is maintained, high vibration-resistance can be achieved by reliable anchoring of the circuit components, the weight can be reduced easily, and which has excellent operational stability. An inverter-integrated electric compressor has an embedded motor and has a substrate provided with a motor drive circuit which contains an inverter. In the inverter-integrated electric compressor, after electrical components including the substrate have been affixed within a housing space enclosed by a compressor housing and have been assembled, the housing space is filled with an insulating resin, and at least a portion of the electrical components is sealed by means of the solidified filling resin. The inverter-integrated electric compressor is characterized in that a resin frame, which has a concave retaining part equipped with a concave part formed in a concave shape along the exterior form of the circuit components
