PROBLEM TO BE SOLVED: To provide an OF cable capable of feeding large electric power. SOLUTION: An OF cable has an insulating layer 3 impregnated with insulating oil on the outer periphery of a conductor 1. At least a portion of the insulating layer 3 is formed by alternately winding a laminate sheet, to which a craft sheet is bonded, and an insulating tape of an independent plastic film on both sides of a plastic film. With the laminate sheet and the insulating tape alternately wound, the percentage of a plastic occupied in the insulating layer 3 is larger and an oil passage is kept.
