Abstract: A wind turbine blade includes: a blade body portion; and an anti-erosion layer disposed so as to cover a surface of the blade body portion partially. A center point of the anti-erosion layer in a circumferential length direction along a blade profile in a cross section orthogonal to a blade spanwise direction is shifted toward a pressure side from a leading edge of the blade body portion, at least in a part of an extension range of the anti-erosion layer in the blade spanwise direction.
