The invention concerns a heating pane consisting of at least a rigid glass pane, at least two collector bars of current of different polarity arranged substantially parallel to a ridge of the heating pane at different distances relative to the ridge and linear heating resistors electrically connected thereto. The invention is characterised in that the collector bars extend laterally relative to the heating resistors and the heating resistors (2) are, starting from a first current collector bar (4) brought back by passing over above the other current collecting bar (3) while being isolated relative thereto, in the direction of the pane surface and in at least one loop towards the other current collector bar (3) and are electrically connected thereto.
