ABSTRACT:
A panel heating element, especially for thermal home appliances, with a laminar support element (1) for supporting all items to be heated and an electrically conductive heating layer (2) applied laminarly to support element (1), the heating layer (2) containing glass and being applied in a pasty state. The panel heating element makes possible a relatively high surface-specific heating power and relatively high heating temperatures and, moreover, is relatively inexpensive in that the heating layer (2) in pasty state consists of powdered molybdenum boride, of two different powdered types of glass and of an organic substance, and, in the preferred embodiment, an insulating layer (3) is provided between the support element (1) and the heating layer (2), and the heating layer (2) is provided with a protective layer (4) on a side that faces away from support element (1).
