The present invention describes a windowpane, in particular vehicle windowpane, having at least one flat-conductor soldered connecting element for making electrical contact, which flat-conductor soldered connecting element has at least one electrically insulating plastic layer and one electrically conductive layer or foil which is connected to a soldering surface for soldering on a line connection which leads on from the windowpane, and which flat-conductor soldered connecting element is adhesively attached to an outer surface of the windowpane, characterized in that at least one electrically insulating buffer layer is provided between a section of the electrically conductive layer or foil with a freely exposed soldering surface, on the one hand, and the surface of the windowpane, on the other.
