<P>PROBLEM TO BE SOLVED: To configure a multi-core electric wire which enables arranging a conductor without clearance to increase current capacity and has a strand conductor with a form, insulation method and configuration method in which skin effect is low even if a high frequency current is applied. <P>SOLUTION: A plurality of conductor wires 12 whose minor axis is smaller than twice the skin depth are provided inside a hollow conductor tube 15 whose wall thickness is smaller than the skin depth, and the plurality of conductor wires 12 and the hollow conductor tube 15 are integrated via an insulator film 13 to form a multi-core electric wire 10. A cross-sectional outline of the multi-core electric wire 10 is circle, rectangle or regular hexagon. <P>COPYRIGHT: (C)2012,JPO&INPIT |
