PROBLEM TO BE SOLVED: To provide a structure of a stator by which the efficiency of a motor is improved. SOLUTION: The structure of the stator has a hollow jacket with a first end and a second end, a plurality of first projecting teeth, which are connected to the first end at intervals and extended to a first plane, and a plurality of second projecting teeth which are connected to the second end at intervals and extended to a second plane. When the first projecting tooth is projected to the second plane along in the axial direction of the hollow jacket, the first projecting tooth is located between the second two adjacent projecting teeth. The hollow jacket and the first/second projecting teeth include a body to be integrally formed, an insulator formed on the outer face of the hollow jacket, a coil wound around the insulator, a circuit board installed under the second projecting tooth, and a stator bracket jointed and fixed to the hollow jacket.
