摘要： A wind turbine blade comprises a profiled contour having a pressure side and a suction side, a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge. The profiled contour generating a lift when being impacted by an incident airflow is formed by a hollow shell body. The hollow shell body is formed by at least a first shell body part and a second shell body part, which are mutually connected at least at the trailing edge and/or the leading edge. An edge stiffener is arranged within the hollow shell body at a first part of the edges, a first surface part of the edge stiffener being connected to an inner side of the first shell body part, and a second surface part of the edge stiffener being connected to an inner side of the second shell body part.
