A small stepping motor has a rotor comprised of a rotatably mounted and radially magnetized permanent magnet having a plurality of magnetic poles, a stator having a plurality of magnetic pole portions positioned to face the rotor, a coil wound around the stator, and a driving circuit for controlling the exciting current supplied to the coil. A leakage flux converging member is positioned in the vicinity of the stator so that leakage magnetic flux from the stator or the coil is converged by the leakage flux converging member so as to pass through the stator.
