Cooking apparatus heating device having:at least one electric heating plate (10, 12, 14), electric conductors (16) for supplying the plates, coupled to at least one of the plates, a dielectric layer in contact on one side with conductors (16), while the other side makes direct contact with the plates. Independent claims are included for: (1) a cooking apparatus with at least one heating plate; (2) a process for preparation of the cooking apparatus by mixing a sol/gel solution with up to 90 wt.% of a solution of electrically conductive powder to give a stable dispersion, where the powder is selected from:ceramics, metals, or semiconductors, coating of the dispersion onto a substrate, and stoving of the substrate.
