A wind turbine blade includes a laminated structure having an outer shell (1) having a shape of the blade, an upwind-side reinforcing section (4a) which reinforces a upwind-side part of the blade in the outer shell 1 and a downwind-side reinforcing section 4b which reinforces a downwind-side part of the blade in the outer shell 1. The outer shell 1 includes a first multidirectional material, a first unidirectional reinforcing material 12 and another multidirectional material 11 which are layered. The upwind-side reinforcing section 4a includes another unidirectional reinforcing material 12 provided between the first unidirectional reinforcing material 12 and another multidirectional material 11. The downwind-side reinforcing section 4b includes yet another unidirectional reinforcing material provided between the unidirectional reinforcing material 12 and the multidirectional material 11. The outer shell 1 includes a first core member 13 respectively provided between the upwind-side reinforcing section 4a and the downwind-side reinforcing section 4b on a leading edge side, and between the upwind-side reinforcing section 4a and the downwind-side reinforcing section 4b on a trailing edge side.
