Abstract
A molded part is formed of an insulating resin such that a stator, electronic components, and a circuit substrate are included inside the molded part. A protective layer for preventing breakage of electrical connection that might occur due to expansion or shrinkage of the molded part is provided at least between the electronic components and the molded part. The protective layer is formed of an insulating material having shear adhesion strength smaller than that of an insulating resin of the molded part that has been cured. The shear adhesion strength and the thickness of the protective layer are defined so that, when the expansion or shrinkage which might cause the breakage of the electrical connection has taken place in the insulating resin of the molded part, separation between the electronic components and the protective layer can be caused.
