description The utility model relates to a fan blade, an impeller and an axial flow fan, and the fan blade comprises a blade body which is provided with a suction surface and a pressure surface which are opposite; the wing-shaped bodies are arranged on one side of the suction surface of the blade body and distributed at intervals in the spanwise direction of the blade body, the geometric dimensions of the multi-stage wing-shaped bodies and the included angles between the multi-stage wing-shaped bodies and the blade body are different, the wing-shaped bodies extend to the tail edge from the front edge of the blade body, and molded lines of the wing-shaped bodies are fitted curves; the front edge and the tail edge are arranged at the two ends of the rotating direction of the blade body, and the spanwise direction refers to the length direction from the blade root to the blade tip of the blade body. According to the blade, the multi-stage bionic airfoil-shaped body is arranged on one side of the suction surface of the blade
