ルド樹脂部３との間にすき間を生じやすいためである。However, in the above-mentioned conventional structure, water penetrates through the joint portion between the lead wire 1 and the first mold resin portion 3 to lower the water resistance and moisture resistance. The reason is that a gap is easily generated between the lead wire 1 and the first mold resin portion 3 that molds the lead wire 1 due to the influence of the softening agent of the resin of the lead wire.

向に向う凹部を形成するものである。In order to achieve the above object, the present invention is a molding method in which a connecting fitting is connected to a tip of a lead wire and a predetermined length used for connection is left at the tip of the connecting fitting. The first mold resin portion, the motor stator winding, and the connection fitting are connected to each other, and then the second mold resin portion is molded around the outer periphery of the first mold resin portion. A concave portion facing the lead wire is formed on the outer periphery of the resin portion.
