Claims

[Scope of Claim for Utility Model Registration] (1) A linear core string made of an elastic material that can be expanded and deformed, and a round conductor wire and a foil conductor wire wound around the core cord in a spiral shape at appropriate pitches. 1. A bend-resistant and stretchable electric wire comprising a conductor and an insulating layer surrounding and covering the conductor with an elastic material similar to the core string. (2) The bend-resistant and stretchable electric wire according to claim 1, wherein the elastic material that can be freely drawn and deformed is a polyurethane elastomer elastic material. (3) The bending resistance according to claim 1 of the utility model registration claim, characterized in that the lower layer is a round conductor and the upper layer is a foil conductor having a width wider than the diameter of the round conductor, which is wound in a spiral shape. elastic and stretchable wire.
