PROBLEM TO BE SOLVED: To provide a stepping motor which can improve inconvenience such as wire breakage, etc. in assembling work by suppressing the inclination of a terminal caused by the slip out or the play of a terminal or the distortion or deformation of a bobbin. SOLUTION: This stepping motor is equipped with a rotor which has s magnet 4 magnetized in multipoles and a stator which is counterposed to the magnet. The stator has combtoothed yokes 5a, 7a, 5b, and 7b opposed to the magnet 4 and coil bobbins 8a and 8b caught between the yokes. The coil bobbin has extensions 16a and 16b where mounting holes 15a and 15b for attaching terminals 10a and 10b connected with a coil 18 are formed. The terminals 10a and 10b are provided with mounting bases 17a and 17b which have functions of preventing the slip out from the mounting holes at their one-side ends. The other end is projected outward from the extension via the mounting hole, and a heat-resistant insulating member 9 is interposed between the extension of the coil bobbin and the yoke.
