Zusammenfassung:	A flow path forming guide to form a flow path within a hollow gas turbine blade according to an embodiment of the present invention comprises: a ceramic core comprising a flow path forming body having a shape bent several times, and a pocket forming body spaced from the flow path forming body; and a plurality of support pins connecting the flow path forming body and the pocket forming body. Here, the support pins may contain a material with a higher thermal shock coefficient than that of the ceramic core. 일 실시 예에 따른 중공형 가스터빈 블레이드 내에 유로를 형성하기 위한 유로 형성 가이드는, 복수 회 절곡된 형상을 갖는 유로 형성 바디와, 상기 유로 형성 바디로부터 이격되어 있는 포켓 형성 바디를 포함하는 세라믹 코어; 및 상기 유로 형성 바디 및 상기 포켓 형성 바디를 연결하는 복수 개의 지지 핀을 포함하고, 상기 지지 핀은 상기 세라믹 코어보다 열충격계수가 높은 재료를 포함할 수 있다.
