Abstract
A heating unit with a resistive element formed as a conducting pattern, which resistive element is bound to a substrate, such as a base plate, on which the resistive element is extended, and which resistive element is arranged to be placed under the influence of an electrical voltage. The invention is wherein the resistive element and the said base have the same or essentially the same coefficients of thermal expansion, and in that the resistive element has been bound to the substrate by sintering.
