ABSTRACT:
A spacer for mounting around the outer peripheral surface of a bobbin. The spacer has first and second edge surfaces formed in a circular arc shape. Subsequent to the formation of a first coil by winding wire around the bobbin, the wire is continuously curved from a distal end portion of the first coil along the first edge surface of the spacer. After making a U-turn of substantially 180 degrees, the wire is wound to form the second coil. Upon completion of winding of the second coil, the wire is guided along the second edge surface, from an end portion of the second coil, and a second portion of the first coil is wound. The portion of the wire for connecting both of the first and second coils is free from bent corners, thus avoiding the generation of stress concentration. Also, the wire is guided by smooth and curved edge surfaces of the spacer, thus preventing damage to a coating on the wire.
