Beschreibung
Zusammenfassung:	A vane-shaped portion (11) is comprised of cooling chambers (C1, C2, C3) corresponding to spaces that extend in the longitudinal section direction of a vane and are obtained by dividing the inside of the vane-shaped portion (11) into a plurality of spaces from a front edge (LE) toward a rear edge (LE) using partition walls (P), which are provided with partitioning portions (22) on the inner wall of a vane body (21); insertion tubes (31) which are disposed in the cooling chambers (C1, C2, C3) and are provided with a plurality of impingement holes (34); and film holes (23) provided in the vane body (21). Each insertion tube (31) is provided with a partition portion (32) which extends from the front edge (LE) toward the rear edge (TE), and also extends in the longitudinal section direction of a vane. The inside of the insertion tube (31) is divided into positive pressure surface-side insert spaces (IP1, IP2) on the side of the positive pressure surface and negative pressure surface-side insert spaces (IS1, IS2) on the side of the negative pressure surface.
