A flat, surface mounted, flexible, multi-purpose wire has a plurality of flat elongated conductors spaced apart in a generally parallel relationship. Each of the flat conductors comprises a plurality of copper layers. An adhesive material separates the flat conductors and an insulation layer surrounds the flat conductors and the adhesive material, with the adhesive material bonding to the insulation layer. A cross-sectional height of the flat conductors and insulation layer is such that the multi-purpose wire will blend in with the surface when painted or after wallpaper is applied.
