Abstract
Provided is an inverter-integrated electric compressor having high heat resistance, which is capable of suppressing thermal interference among a plurality of power devices. Specifically provided is an inverter-integrated electric compressor which comprises a built-in motor and a substrate provided with a motor drive circuit including an inverter, an electric component including the substrate being affixed in a housing space surrounded by a compressor housing, wherein a plurality of power semiconductor elements which constitute the motor drive circuit are disposed radially around a drive shaft of the motor in a plane crossing the drive shaft. For example, the planar shape of the power semiconductor element is formed into a rectangle, and a gap having a sectorial planar shape is formed between the power semiconductor elements adjacent to each other.
