Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a litz wire which is suitable for a coil used in a frequency band of 50-150 kHz of a non-contact power feeding system of an electromagnetic induction type.SOLUTION: A litz wire is formed by: intertwining plural primary stranded wires formed by intertwining plural strands for forming a secondary stranded wire; then intertwining plural secondary stranded wires. A cross section of the litz wire has a uniform division structure by the plural secondary stranded wires, and a distance between strands on each division area is 3-15 μm.SELECTED DRAWING: Figure 2 【課題】電磁誘導型の非接触給電システムにおいて５０〜１５０ｋＨｚの周波数帯で使用されるコイルに好適なリッツ線を提供する。【解決手段】リッツ線は、複数本の素線を撚り合わせてなる一次撚り線を複数束撚り合わせて二次撚り線とし、さらに二次撚り線を複数束撚り合わせた構成を有する。リッツ線の断面は複数束の二次撚り線による均等分割構造を有し、それぞれの分割領域における素線間距離はいずれも３〜１５μｍである。【選択図】図２
