Disclosed in the invention is a multi-concave-plane propeller comprising a propeller hub and a blade. A thrust surface of the propeller blade is formed by a plurality of concave planes at the radial direction. Compared with the prior art, the multi-concave-plane propeller has the following beneficial effects: the thrust surface of the propeller blade is formed by a plurality of concave planes at the radial direction and the large thrust force can be provided with the same protection area; and the radial streaming can be reduced and thus the propeller with the high thrust efficiency can be provided.
