The invention describes a de-icing arrangement (1) of a wind turbine rotor blade (2), which de-icing arrangement (1) comprises an electrically conductive mat (10); an electrically conductive band (11) for distributing an electric current along a first edge of the mat (10); and a current supply connector (12) for connecting the band (11) to a current supply (13); wherein at least the electrically conductive mat (10) is embedded in the body of the rotor blade (2). The invention further describes a wind turbine (3) comprising a number of rotor blades (2) comprising such a de-icing arrangement (1) according, and a current supply (13) for connecting to the de-icing arrangements (1) of a rotor blades (2). The invention also describes a method of incorporating a de-icing arrangement (1) in a wind turbine rotor blade (2).
