1. A method of manufacturing a wind turbine blade comprising:
performing spar cap formation in which a first-type spar cap having a structure in which support plates including reinforcing fibers are stacked and a second-type spar cap including reinforcing fiber sheets are formed;
performing shell formation in which a pressure side shell and a suction side shell are formed by injecting a resin in a state in which the first-type spar cap, the second-type spar cap, and a core panel are disposed between an inner skin and an outer skin; and
performing shell assembly in which the pressure side shell is joined to the suction side shell,
wherein, in the performing shell assembly, the first-type spar cap is coupled to one end of a shear web and the second-type spar cap is coupled to the other end of the shear web.
