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 method of obtaining a substrate coated on a first face with at least one transparent and electrically conductive thin layer based on at least one oxide, including depositing the at least one thin layer on the substrate and subjecting the at least one thin layer to a heat treatment in which the at least one layer is irradiated with aid of radiation having a wavelength between 500 and 2000 nm and focused on a zone of the at least one layer, at least one dimension of which does not exceed 10 cm. The radiation is delivered by at least one radiation device facing the at least one layer, a relative displacement being created between the radiation device and the substrate to treat the desired surface, the heat treatment being such that resistivity of the at least one layer is reduced during the treatment.
