PROBLEM TO BE SOLVED: To propose a small-sized stepping motor of high durability. SOLUTION: Insert molding is performed with resin so as to integrally cover all of a plurality of terminals for power supply which are protruded at peripheral edges of a pair of armature coil bobbins. Peripheries of two magnetic cores which are sandwiched between the coil bobbins are not covered by the insert molding. A sealing means like an O ring is arranged between a motor side connector formed by the insert molding and a connector cover engaged with the connector. A part between a connector lead wire assembly which is led from the connector cover and whose periphery is covered with a tube and the connector cover is sealed with an adhesive agent. In the connector lead wire assembly, a part in the vicinity of the connector cover is so bound tightly with a fastening band and fixed that the tube and the plurality of lead wires are not shifted.
