An apparatus for manufacturing a taped insulated conductor and a method of controlling a tape winding tension. The apparatus comprises a wire material feeder feeding a wire material, a tape winder winding a tape body on the wire material fed from the wire material feeder, and a receiving device receiving the wire material on which the tape body is wound by the tape winder. A rotating shaft torque is controlled to a prescribed torque by rotatingly driving a tape pad fixing part by a torque gradually decreasing control without relying on the number of the windings of the tape body. Thus, the delivery tension of the tape body can be set to a specified prescribed value.
