A permanent magnet type stepping motor wherein magnetic poles of a stator core (1) consisting of a cylindrical yoke (22-1) (22-2), a plurality of magnetic poles (1-2) provided radially around the inside of the cylindrical yoke (22-1) (22-2), and pole teeth (4-1) (4-2) formed on the tips of the magnetic poles (1-2) are divided into two almost equal parts near the tips thereof so as to be isolated axially from each other, each of the pole teeth (4-1) 4-2) of the magnetic poles (1-2) in each group is made to face one of pole teeth (9) of two poles (8) provided around the circumference of a rotor with a gap therebetween.
