The present invention has an object to provide an inverter module and an inverter integrated electric compressor capable of reliably suppressing noise interference on a control circuit board and facilitating filling with a resin gel material. Provided is an inverter module including a power system circuit board and a control circuit board (30) that are integrated through a resin case, in which an insulating through hole (47) is provided in a region between: a frame ground (42) connected to a high voltage system formed on the control circuit board (30); and a low voltage circuit (46) adjacent to the frame ground (42).
