LITZ WIRE, LITZ WIRE COIL, AND METHOD FOR MANUFACTURING LITZ WIRE

摘要

Provided are a litz wire, a litz wire coil, and a method for manufacturing a litz wire. This litz wire is a litz wire for a high-frequency non-contact feed coil used in a frequency band of 50-150 kHz, and is constructed by twisting a plurality of primary stranded wires each obtained by twisting a plurality of element wires to make a secondary stranded wire, and further twisting a plurality of the secondary stranded wires. The cross-section of the litz wire has a structure equally divided by the plurality of secondary stranded wires, and any of distances between element wires in each divided region is 3-15 μm.
