PROBLEM TO BE SOLVED: To provide a stator of a motor which can be disassembled easily and can readily meet the demand of sorted collection for recycling. SOLUTION: In the stator 1 of a motor where a coil bobbin 20 is applied to the tooth part 12 of a stator core 10 and a stator coil 30 is wound from above, the tooth part 12 of the stator core is tapered such that the circumferential side face becomes narrower from the base end toward the forward end. The coil bobbin 20 is formed as an integral annular component having inner circumferential wall corresponding to the tapered shape of the tooth part 12 of the stator core. The coil bobbin 20 is fitted, from the forward end thereof, over the tooth part 12 of the stator core and shrink fitted. Under that state, a beveled part 24 at the end part of inner circumferential wall of the coil bobbin 20 is made to engage resiliently with the forward end engaging protrusion 13 of the tooth part 12 thus positioning and locking the coil bobbin 20.
