(57) [Abstract] [PROBLEMS] An insulation coating treatment that is extremely excellent in insulation, corrosion resistance, adhesion, heat resistance, magnetic property improvement effect, etc., without insulation treatment of the end face of the iron core without pretreatment such as degreasing and annealing. Is proposed at a low temperature in a short time. SOLUTION: The surface roughness of the unevenness of the laminated steel sheet including the return after punching of the iron core material is 5 to 50 μm, and the outer surface (end face or upper and lower faces) of the laminated iron core has an average film thickness of 0.5 μm. A rotating electric machine for a vehicle, wherein a dry insulating film of an organic silicon compound having a voltage of 5 to 30 μm and a withstand voltage of 60 V or more is formed, and a conductive member is disposed so as to face the dry insulating film, and a method of manufacturing the same. |
