Abstract: An inverter-integrated electric compressor configured in such a manner that a motor is incorporated within a compressor, a control circuit board is provided to an inverter section which is provided with a motor drive circuit for driving the motor, and electric component parts including the control circuit board is fixed within a containment space surrounded by a compressor housing, wherein the control circuit board is fixed within the housing space through a board-fixing section, and a board vibration-isolating member, said board vibration-isolating member consisting of an electrically insulative elastic material, is provided between the control circuit board and the board-fixing section. A frame member having a convcave holding section may be loaded on the control circuit board, and a board vibration-isolating member, said board vibration-isolating member consisting of an electrically insulative elastic material, may be provided between the control circuit board and the frame member.

Abstract: 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 a built-in motor and has a substrate provided with a motor drive circuit including an inverter. In the inverter-integrated electric compressor, after electric components including the substrate have been fixed in a housing space surrounded by a compressor housing and have been assembled, the housing space is filled with an insulating resin, and at least a part of the electric components are sealed by the solidified filling resin.
