ABSTRACT:
A contact heat-transferring electric hotplate (11) is provided, which is made from nonoxidic ceramic, particularly silicon nitride. Its very thin hotplate body (14) in the form of a disk is installed in self-supporting manner in a hob plate, e.g. by bonding, and has an extremely flat surface or which is adapted to the cooking vessel shape, which creates such a small gap with respect to said vessel that a coupling is possible even with higher power densities with only a temperature difference of a few degrees. The heating means (17) is also in contact with or directly connected to the underside of the hotplate body (14).
