description The utility model relates to an axial flow fan blade, an axial flow fan and an air conditioner, wherein the axial flow fan blade comprises a blade front edge and a blade tail edge, and two or more groove structures sunk in the direction of the blade front edge are formed in a blade tail edge area in the radial direction. According to the axial flow fan blade, the axial flow fan and the air conditioner, the vortex intensity at a suction surface of the axial flow fan blade can be effectively weakened through the multiple groove structures, and impact generated by wake vortexes of a front axial flow fan blade toward a back axial flow fan blade is reduced so that air volume can be effectively increased, noise of the axial flow fan can be reduced, and weight of the axial flow fan blade can be decreased.
