Coil winding apparatus and coil winding method

A coil winding apparatus comprising:

• a cylindrical core rod nozzle having an outer diameter smaller than a natural outer diameter of a string-shaped core rod and configured to allow insertion of a narrowed core rod;
• a wire rod feeding unit configured to feed a wire rod to the core rod nozzle;
• a wire rod holding tool configured to hold the wire rod fed from the wire rod feeding unit;
• a wire rod winding unit configured to wind the wire rod fed from the wire rod feeding unit around the core rod nozzle by rotating the wire rod holding tool around the core rod nozzle;
• a core rod drawing unit configured to draw the core rod from the core rod nozzle;
• and
• a coil drawing unit configured to draw a wound wire formed by winding the wire rod on an outer periphery of the core rod nozzle from the core rod nozzle.
