Abstract
A shielded electric wire having an electric conductor, a high expansion insulating layer provided on the electric conductor, a rigid skin layer on the insulating layer, and a closed shield layer on the skin layer. The closed shield layer is produced by winding a number of electric wires on the insulating layer at a winding angle of 80.degree.-85.degree. from the normal to the longitudinal axis of the conductor. This electric wire is free from changes in its characteristics even if the degree of expansion of the insulating layer is as high as 65% or more and thus is suitable for use in wiring electronic devices such as computers.
