The method for producing a electroconductive sheet having a substrate, in particular made of paper, and an electroconductive layer include the steps of: a/ preparing a multi-layer structure with an anti-adhesive coating inserted between a plastic film and a base layer, b/ cross-laminating the multi-layer structure and the substrate, and c/ removing the plastic film and the anti-adhesive coating from the base layer. The base layer is a layer of an electroconductive material or is covered with an electroconductive layer by an additional step consisting of: d1/ depositing an electroconductive film on the base layer; or d2/ printing the base layer with at least one ink having electrical properties, with the base layer being a printable layer with a binder base of which the rate is 15% greater in dry weight in relation to the total dry matter weight of this layer.
