Abstract: In a method to manufacture a stator by coupling a plurality of core segments as so to compose a serial body of core segments and rounding the serial body into an annular body, a stator which method can secure an optimum length of a connected wire by preventing the connecting wire from being too long or too short between the core segments at a stage to round the serial body of core segments into the annular body and method of manufacturing thereof are provided. A member to form a motor stator is composed of a plurality of core segments which are movably coupled, a plurality of insulators which cover the core segments and have head portions having spaces allowing a connecting wire to pass therethrough, and the coil wire which is wound around the core segments to form a coil and serves as a connecting wire passing through the head portions, the member being capable of securing an optimum length of the connecting wire.
