Abstract
The flat electrical resistance heating element is intended principally for a household article having a heating surface. The heating element comprises a heating resistance cut out from a metal sheet (1) which is coated with a substrate (2) of electrically insulating material resistant to the heating temperature and adherent to the metal sheet (1) and to the material of which the support (5) of the heating surface of the article is made. Use principally in base-heated kitchen utensils and irons.
