Abstract: In order to produce resonance labels a coil having the shape of a spiral and a first capacitor surface located adjacent the innermost winding of the spiral and, furthermore, a supplementary surface adjacent the outer end of the spiral are produced at one side only of a supporting foil by an etching method from an aluminum foil arranged on the supporting foil. An aluminum foil strip is sealed onto the other side of the supporting foil at a superimposed position relative to the first capacitor surface, a few windings of the spiral and the supplementary surface to form the second capacitor surface. After establishing an electrical connection between this strip and the supplementary surface at the other side an electrical resonant circuit is produced. Due to the sealed on aluminum foil strip the etching procedure is reduced to only one side with the advantage that considerably less poisonous etching sludge is thus produced.
