Abstract
A wind turbine blade is provided, which includes a blade body extending from a blade root toward a blade tip along a blade length direction, a first sprayed layer disposed so as to cover at least a leading edge on a side of the blade tip of the blade body, for suppressing erosion of the leading edge of the blade body, a second sprayed layer formed between the blade body and the first sprayed layer, and having a lower electrical resistivity than the first sprayed layer, and a first conductive part for electrically connecting the second sprayed layer to a ground.
