A stator used for a motor and having excellent vibration resistance, waterproofness, and an insulating property. The stator used for a motor includes a stator core having a plurality of teeth arranged at substantially equal intervals on a same circumference, and an insulator covering the teeth, and coil portions are formed by wires being winded around portions of the insulator that covers the plurality of teeth. The insulator includes first wall portions provided on the center axis side with respect to the coil portion, and molded portions formed, by resin, on the center axis side with respect to the first wall portions. Wire extended portions of the wire pulled out from the coil portion straddle the first wall portions. Wire terminal end portions are connected to bus rings. The bus rings are embedded in the molded portions.
