Abstract
A wind turbine blade using a core member that is light and low-cost while maintaining strength and a wind power generator using the same are provided. A wind turbine blade (9) is formed of a fiber-reinforced plastic skin (13). The skin (13) or a main beam (15) uses a core member (39) formed integrally of fiber layers (55) arranged so as to intersect in plan view and each penetrate in the thickness direction to constitute flow paths for resin and plastic foam members (57) filling spaces between the fiber layers (55), in such a manner that the fiber layers (55) are impregnated with the resin.
