Abstract
A composite blade includes an airfoil; and a blade root including a straight section from a blade end part being a connection location with the airfoil to an inclination start part between the blade end part and a base end, and a bearing section from the inclination start part to the base end. A laminate of composite layers with reinforced fibers impregnated with resin is provided across the airfoil and the blade root. A metal body is provided on the blade root. The laminate extends along the longitudinal direction in the airfoil and in the straight section, and extends to be inclined away from a center axis in the bearing section. The metal body is provided on both surfaces of the laminate in the blade root, extends along the longitudinal direction in the straight section, and extends to be inclined away from the center axis in the bearing section.
