Abstract
An object of the present invention is to provide an inverter integrated motor that achieves both improvement in cooling performance of a current sensor and downsizing of an entire device. An inverter integrated motor includes: a power module that converts a direct current into an alternating current; a flow path forming body that is formed so as to flow and cover a refrigerant in the power module; an inverter that installs the power module and the flow path forming body inside; a current sensor that detects the alternating current; and a motor that houses a stator and a rotor, wherein the power module is disposed at a position facing a rotation shaft of the motor via the stator and the rotor, and the current sensoris disposed between the flow path forming body and a coil end of the stator when viewed from a direction perpendicular to the rotation shaft, and at least a part of the current sensor is housed in a motor housing.
