A wind turbine blade comprising: an elongated blade body extending along a longitudinal axis and having a blade root at one longitudinal end of the blade body and a blade tip at another longitudinal end of the blade body; a leading edge and a trailing edge, both extending from the blade root to the blade tip, the trailing edge spaced from the leading edge in a span-wise direction of the blade body; an upper skin and a lower skin extending from the leading edge to the trailing edge and from the blade root to the blade tip, the lower skin spaced from the upper skin in a thickness direction of the blade body, the upper skin and the lower skin defining a space therebetween, the upper skin and/or lower skin comprises: a laminated layer (124, 126) extending from the blade root towards the blade tip and at least adjacent from or from the leading edge towards the trailing edge, the laminated layer (124, 126) having: an outer layer wherein the outer layer forms part of the upper and/or lower skin respectively; an inner layer spaced from the outer layer in the thickness direction of the blade body; and an intermediate layer sandwiched between the outer layer and inner layer, the intermediate layer having: a plurality of openings extending through the intermediate layer from the inner layer to the outer layer; a plurality of corresponding heat conductor elements extending through the plurality of openings from the inner layer to the outer layer for transferring heat from the inner layer to the outer layer; and characterized in that the blade further comprises heat transfer paths adjacent the inner layer and within the space between the upper and lower skins, the heat transfer paths extending longitudinally from the blade root towards or to the blade tip for conducting heat from the blade root towards or to the blade tip so as to transfer the heat to the heat conducting elements via the inner layer. an elongated blade body extending along a longitudinal axis and having a blade root at one longitudinal end of the blade body and a blade tip at another longitudinal end of the blade body;
