摘要:
A stator includes a base board, a plurality of coil patterns patterned on one face of the base board, a stator core having a ring-like portion formed in a ring-like shape, a plurality of teeth base ends of which are fixed to the ring-like portion and front end portions formed respectively at front ends of the plurality of teeth in which the coil patterns and the teeth are laminated onto the base board to be respectively opposed to each other, and covers having base members bonded to the base board in a state of being respectively fitted to the plurality of teeth 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.
