PROBLEM TO BE SOLVED: To provide a stator of an electric motor which can efficiently cool heat generated at a winding. SOLUTION: This stator of the electric motor is constituted of a laminated body formed by laminating electromagnetic steel plates, and comprises a stator core in which widths of tooth parts at both ends in the lamination direction are smaller than the width of a tooth part at the center, an insulating body formed on the surface of the tooth part by molding the stator core of an insulative resin, and the winding attached on the insulation body.
