The invention proposes a radiative fin (1) for a spacecraft, comprising:- an end fitting (10) of heat conductive material, adapted to be mounted on the spacecraft,- a flexible radiative laminate (20), connected to the end fitting at one end and having an opposite free end, and comprising :∘ at least one pyrolytic graphite sheet, and∘ at least one heat emission layer in contact with the pyrolythic graphite sheet on at least part of the surface of the pyrolythic graphite sheet, and- a flexible rod (30), extending from the end fitting (10) along at least part of a side of the flexible radiative laminate (20) and being affixed to the latter, wherein the flexible rod (30) is adapted to occupy a folded position and a deployed position and to exert, while in the folded position, a deployment torque adapted to bring the flexible rod back to the deployed position.
