Abstract

A controller-integrated rotating electric machine includes a rotating electric machine having a rotor, a stator, and a housing, and a controller having a plurality of switching element modules. Cooling fins having insulating coatings on surfaces thereof facing the switching element modules are bonded to the switching element module. The controller-integrated rotating electric machine of which the cooling fins are electrically insulated by having the cooling fins having the insulating coating on the surfaces facing the switching element modules, so that the electrolytic corrosion between the cooling fins and the heat sinks of the switching element modules is suppressed from occurring.
