A transparent pane with a conductive coating extending at least over a part of the transparent pane surface, in particular over a visual field of the transparent pane is described. The conductive coating is electrically connected to at least two strip-shaped bus bars such that after application of a supply voltage, a current flows over a heating field formed by the conductive coating. The conductive coating has an electrical resistance such that upon application of a supply voltage in the range from more than 100 volts to 400 volts, a heating output from the heating field is in the range from 300 watt/m2 to 1000 watt/m2. The at least two strip-shaped bus bars have a maximum width of less than 5 mm and are dimensioned such that a maximum electrical power loss per unit of length is 10 watt/m. Moreover, the at least two strip-shaped bus bars have a specific resistivity ranging from 2 μohm·cm to 4 μohm·cm.
