    • A heating structure for use in an appliance, the heating structure being a sandwich structure composed of two rigid elements constituting external elements of the sandwich structure, with at least one of the rigid elements being a heating plate; a heating unit composed of an electrical resistance component disposed between the rigid elements for producing heat which is diffused through the rigid elements, and electrical insulation material covering the electrical resistance component; and bonding layers securing the heating unit to the rigid elements. The heating unit further includes a primary layer of thermoplastic resin material into which the electrical resistance component is inserted, the electrical insulation material is composed of first and second layers of electrical insulation material which enclose the electrical resistance component, and the primary layer of thermoplastic resin material adheres to the layers of electrical insulation material. The bonding layers include a second layer of thermoplastic resin material disposed between, and adhering to, the heating plate and the first layer of electrical insulation material.
