Abstract:
In this drive device, a rotating electric machine-side flow path and an inverter-side flow path are connected via a contact surface where a rotating electric machine housing and an inverter housing are in contact with each other. The inverter-side flow path comprises: a first flow path that is linearly provided in an extended manner in a direction separated from a portion connected to the rotating electric machine-side flow path; and a second flow path that branches from the first flow path and circulates within the inverter housing.
