Zusammenfassung:	A gas turbine blade of the present invention wherein a cooling flow path to cool a leading edge and a trailing edge is formed on both sides in the blade, and a plurality of middle part cooling flow paths are formed in between the leading edge and the trailing edge to circulate cooling air; provides a gas turbine blade with a cellular structure whose middle part has a reinforced strength wherein the cooling flow path on the leading edge and the middle part cooling flow paths are made of a pipe; and a cellular structure made of a combination of a plurality of unit cells (C) placed on the outside of the pipe. 본 발명은 블레이드 내부 양측에 리딩 에지(leadeing edge)와 트레일링 에지(trailing edge)를 냉각하기 위한 양측냉각유로가 각각 형성되고, 상기 리딩 에지와 트레일링 에지 측 사이에 복수개의 중간부냉각유로가 더 형성되어 냉각공기가 순환되는 가스터빈 블레이드에 있어서, 상기 리딩 에지측 냉각유로 및 중간부냉각유로는 관형의 파이프로 이루어지고, 상기 파이프 외측으로 복수의 단위셀(C) 조합으로 이루어지는 셀 구조체가 구비되는 것을 특징으로 하는 셀 구조체로 중간부 강성이 보강된 가스터빈 블레이드를 제공한다.
