The present application discloses a blade and an axial-flow impeller using the same. The present application provides a blade, comprising a blade tip, a blade root, a leading edge and a trailing edge, wherein the leading edge and the trailing edge extend from the blade tip to the blade root, respectively. The blade is capable of rotating about a rotation axis X which is perpendicular to a normal plane.
