Abstract

A heater, in particular a high-temperature heater, for example for domestic heating appliances, in which a layer that produces heat when a current flows through is provided on a carrier material as a heating element, wherein a first electrically conductive layer which is formed from a free-flowing, non-electrically conductive base material and carbon nano tubes dispersed therein is applied to the carrier material, wherein a protective layer is applied to this first layer and at least partly penetrates into the first layer as it is applied, or wherein a functional layer with carbon nano tubes dispersed therein is applied to the carrier material, and wherein the at least one layer or the functional layer makes contact with strip-like contact elements, and the layers applied to the carrier material or the functional layer are heated.
