Abstract: The invention relates to a wind turbine blade formed by outer lateral skins (1) arranged on stringers (2) in the manner of inner longitudinal partitions, the blade root being determined by a cylindrical section (5) which is formed by means of extensions (4) of the outer lateral skins (1) and the stringers (2) forming the structural assembly of the blade body, said blade body being able to be determined by means of longitudinal sections which are attached to anchoring rods through longitudinal holes of the walls of the sections in coinciding portions of the attachment.
