Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an inexpensive and compact motor enabling reduction in vibration and noise.SOLUTION: At least one of an inner peripheral face 11a (radial bearing face) and an inner bottom face 11b (thrust bearing face) of a bearing part 11 and a stator core part 12 are integrally formed by sintered metal. Thus, the relative position of the stator core part 12 with respect to the radial bearing face or the thrust bearing face is highly accurately set, and attraction force between a stator coil 20 and a magnet 6 can be made uniform.
