A modular spar cap structure for wind turbine blades is provided. The modular spar cap structure according to an embodiment of the present invention includes a bar-shaped core member extending in the extension direction of a blade; shear web support members coupled to both sides of the core member to support a shear web of the blade; an upper support member coupled to the upper part of the core member; and a lower support member coupled to the lower part of the core member, wherein the core member, the shear web support members, the upper support member, and the lower support member are modularized. According to the present invention, a blade having high bending rigidity and a stable torsional support structure while having a reduced weight can be provided. 풍력 발전기 블레이드용 모듈형 스파캡 구조체가 제공된다. 본 발명의 일 실시예에 따른 모듈형 스파캡 구조체는, 블레이드의 연장 방향으로 연장된 바 형상의 코어 부재; 코어 부재의 양측부에 결합되어 블레이드의 전단 웹을 지지하는 전단 웹 지지 부재; 코어 부재의 상부에 결합되는 상부 지지 부재; 및 코어 부재의 하부에 결합되는 하부 지지 부재를 포함하고, 코어 부재, 전단 웹 지지 부재, 상부 지지 부재 및 하부 지지 부재가 모듈화되도록 형성된다.
