Inverter-integrated electric compressor

An inverter-integrated electric compressor in which an inverter device including an inverter circuit board is integrally incorporated into an inverter housing section provided in a housing,

• the inverter circuit board being divided into a main circuit board having a shape and size that can be housed within the inverter housing section and a smaller sub-circuit board electrically connected to the main circuit board,
• the main circuit board being affixed and installed to boss sections at a minimum of four corners, and being also affixed and supported underneath by a top area of electrical components mounted to the circuit board, the electrical components having a bottom area being adhered to a concave section of a side section along an axial direction of an outer peripheral wall of said housing, and
• the sub-circuit board having a flaring shape from a front end side to a back end side, and being affixed and installed to boss sections at three points which are one point at the front end side and two points at the back end side in a space below the main circuit board to the back of a bottom section inclined downwards toward the back from the front of the inverter housing section.
