Abstract: A ceiling fan blade for securing to a ceiling fan motor includes a flat root portion and a fan member each having a flange extended from one end and perpendicular to and solidly secured to the root portion and the fan member. The root portion and the fan member are inclined relative to each other for allowing the fan member to be directed toward a relative wind to the ceiling fan blade. The flanges of the fan member and of the root portion of the ceiling fan blade each includes a triangular shape and each includes a longitudinal axis coincident with each other for greatly increasing the strength of the ceiling fan blade.
