Abstract

The invention concerns an electrical element consisting of ceramic material and an electrical resistance 2 arranged in this when casting the material, for heating up the material. According to the invention the element 1 comprises a body layer 3 in which is cast the electrical resistance in the form of a bare resistance wire 2, and an outer layer 4 which is not in contact with the electrical resistance, where there is an interface between the body layer 3 and the surface layer 4 which prevents any crack appearing in the outer layer 4 from continuing into the body layer 3. <IMAGE>
