A PTC heating device exhibits a good degree of efficiency while providing good electrical insulation of the device's PTC element. The insulation of the PTC heating device comprises a film and a layer that is bonded to the film and made of brown compact which comprises non-sintered ceramic particles. Also disclosed is a method in which ceramic particles are provided with a binding agent, and the mass thus produced is applied in a planar manner onto a film and bonded to the film. The multilayer insulation thus produced is placed around the PTC element and the conductor tracks, and the binding agent is subsequently removed, at least in part.
