An inexpensive litz wire coil ensuring sufficiently high space factor and insusceptible to deterioration in characteristics even in high frequency region. Two litz wires (12A, 12B) where the strands equal to one half of a predetermined number of strands are stranded collectively in reverse directions are wound in parallel and shaped into a coil before being pressed into a predetermined shape by means of a die. Since the number of strands of two litz wires(12A, 12B) is set equal to one half of a predetermined number, electrical resistance substantially equal to that of a litz wire coil normally shaped of one litz wire can be attained without increasing the strand diameter or without thickening the insulating film of the strand (14). Since two litz wires(12A, 12B) are stranded collectively in reverse directions, risk of cross-cutting the strands of the litz wire is eliminated when they are pressed thus reducing damage on the strands.
