The invention relates to a heating element comprising a substrate () equipped with a thin-film multilayer, the thin-film multilayer comprising a film () suited to being heated, this film having a sheet resistance of between 20 and 200 &#x3a9;/square, the heating element also comprising two conductive collectors suited to being fed with electrical voltage, the film suited to being heated being a transparent electrically conductive oxide film and the film () suited to being heated not being machined and being electrically connected to the two conductive collectors, the film () suited to being heated having a thickness of between 50 nm and 300 nm. The invention allows a heating element, with a film suited to being heated that is simple to manufacture, to be easily installed in an electric vehicle or easily connected to the national grid.

Film-type heating element

A transparent substrate provided with a stack of thin layers includes an alternation of n functional layers having reflection properties in the infrared region and/or in solar radiation with n&#x2267;2 and of n+1 coatings including one or more dielectric layers, so that each functional layer is positioned between two coatings, the coatings and the functional layers are numbered according to their position with respect to the transparent substrate, the lower coating 1 is placed above the transparent substrate and below the functional layer 1, the intermediate coatings 2 to n are placed between two functional layers and the upper coating n+1 is placed above the functional layer n, wherein at least one of the upper or intermediate coatings 2 to n+1 includes at least one barrier coating including at least two barrier layers, one layer including silicon and one layer based on aluminum nitride.
