Abstract: A spindle motor comprising a base main body, a stator, and a connector means to which a lead portion from a coil of the stator is electrically connected. A core securing portion and a core securing hole are provided in the base main body. The connector menas is provided with a block-shaped connector main body and a plurality of terminal portions disposed in the connector main body, one end portions of the plurality of the terminal portions are exposed to one surface of the connector main body and their other end portions are exposed to the other surface of the connector main body. The stator and the connector are constructed as a unit by connecting lead portions from coils to one end portions of the plurality of the terminal portions. A coil winding apparatus convenient for winding coils on stator cores and connecting one end portions of the coils to the terminal portions of the connector means.
