Classification: CPC F  Y | IPC F

Claim 10:
11. A wind turbine blade, comprising:
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,
wherein the second sprayed layer is formed by copper, a copper alloy, aluminum, or an aluminum alloy, and has a lower hardness and Young modulus than the first sprayed layer,
wherein the blade body includes a receptor connected to the first conductive part,
wherein the receptor is connected to the second sprayed layer, and
wherein the receptor includes a plurality of disk receptors disposed separately from each other on the first sprayed layer.
