Abstract:
1. A stator which is a stator arranged opposedly to a permanent magnet rotated along an axis line, the stator comprising: an insulating base board; a plurality of conductive coil patterns patterned onto one face of the base board at respective angles centering on the axis line; a stator core of a magnetic member including a ring-like portion formed in a ring-like shape centering on the axis line, a plurality of teeth base ends of which are fixed to the ring-like portion and which are formed to extend in a radius direction directed to the permanent magnet at the respective predetermined angles, and front end portions respectively formed at front ends of the plurality of teeth and opposed to a peripheral face of the permanent magnet, wherein the coil patterns and the teeth are laminated on the base board to be opposed to each other; an insulating layer coated on an outer surface of the stator core; and covers including insulating base members bonded to the base board in a state of being respectively fitted to the plurality of teeth laminated on the base board and covering surroundings of the respective teeth and conductive patterns patterned to inner faces of the base members and electrically connected to the coil patterns.
