This invention is to eliminate all of the above-mentioned disadvantages by proposing a heating element intended to be deposited on a metal substrate, e.g., made of aluminium or an aluminium alloy, or even stainless steel, which is capable of delivering high outputs, in particular with a surface/output ratio possibly going as high as values on the order of 40 W/cm2, while at the same time maintaining good dielectric performance levels and/or being capable of delivering an even degree of heat over an entire surface.
