Abstract:
A motor includes a stationary unit and a rotary unit. The stationary unit includes a stator, a base portion having at least one hole extending in the up-down direction, and a flexible wiring substrate. The flexible wiring substrate reaches a position higher than a lower surface of the base portion through at least one hole and is arranged to supply electric power to the stator. The flexible wiring substrate includes a connection portion arranged higher than the lower surface of the base portion and connected to the stator. The connection portion includes a solder portion arranged on a lower surface thereof to cover a portion of a lead wire extending from a coil of the stator. At least a portion of the solder portion is positioned within the hole.
