<P>PROBLEM TO BE SOLVED: To provide a weight-saved electric cable with a large and sure weight-saving effect. Ž<P>SOLUTION: In the electric cable 5 made by twisting two or more insulated wire cores 3 each with an insulator 2 coated on a conductor 1, and having an interposition 7 put in a gap formed between the insulated wire cores 3 and an insulating sheath 4 applied on an outermost layer, a hollow airtight body capable of deforming in a cross-section radial direction of the electric cable 5 is made intercalated as the interposition 7 singly or together with another interposition 6.
