Abstract
A litz wire coil is formed of two litz wires, each having a number of single wires equal to one half of a predetermined number of single wires and each stranded collectively in mutually reverse directions and wound in parallel. The two litz wires are shaped into a coil and then pressed into a predetermined shape by means of a die. Since the number of single wires within each of two litz wires is set equal to one half of a predetermined number, electrical resistance substantially equal to that of a single litz wire coil is attained without increasing the single wire diameter and without thickening the insulating film on the individual wires. Since two litz wires are collectively stranded in mutually reverse directions, risk of cross-cutting the single wires upon pressing is eliminated,
