<P>PROBLEM TO BE SOLVED: To provide a turbine blade for reducing thermal stress generated in a rib partitioning the upstream of neighboring cooling passages. Ž<P>SOLUTION: The turbine blade 1 includes: two systems of serpentine conduits 6a, 7a leading cooling medium supplied from a root part to a tip part of the blade; and the rib 17 partitioning the upstream of the neighboring serpentine conduits 6a, 7a over a longitudinal direction of the blade. The rib 17 has a through-hole 18 passing in a through-thickness direction of the rib 17. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
