Disclosed is a de-icing device for at least one surface portion (8) of a rotor blade (1) liable to be covered with a layer of ice. The device includes: at least one first heating device adapted to permit detachment of at least part of the layer of ice, as well as at least one second heating device including heating elements extending facing only part of the surface portion so as to circumscribe at that location closed-contour zones of the surface portion. The heating elements of the second heating device are adapted to cause breaking of the ice depending on the thickness of the layer of ice, and the first heating device extends at least partly facing the inside of the closed-contour zones.
