A rotor blade for a wind power station includes a profiled member that is provided with a relative thickness which decreases towards the outside from a root to a tip of the blade. The profiled member has a leading edge and a trailing edge as well as a suction side and a pressure side while generating a negative pressure relative to the pressure side on the suction side when being flown against by moved air, the negative pressure resulting in buoyancy. The suction side of the rotor blade encompasses a device for optimizing flow around the profiled member. The device is provided with at least one planar element that extends substantially in the direction of flow, protrudes from the suction side, and is arranged in the zone of a transversal flow which runs from the root to the tip of the blade on the suction side of the profiled member.
