SOLUTION: In the stator core, two or more claw magnetic poles are formed, by using a claw part extending in an axial direction and having each magnetic pole face opposite with a minute gap with a rotor, a radial-direction yoke part extending from the claw part to the outer diameter side, and an outer circumferential yoke, extending from the diameter directional yoke part to the same direction as that of the claw part. The claw magnetic poles are arranged mutually in a circumferential direction, in such a way that the top end of the claw part is made to face the radial-direction yoke part of the adjoining claw magnetic pole in the stator core. A stator is formed, by inserting an annular coil, between the claw magnetic poles adjoining the stator core in the multiple phase claw-pole type motor. The claw magnetic pole is formed by compressing magnetic powder; and at the same time, the claw magnetic pole is formed by compressed powder magnetic core with DC magnetization characteristics of magnetic flux density of 1.7 teslas or higher, when a magnetic field of 10,000 A/m is applied.
