PROBLEM TO BE SOLVED: To provide a turbine such as a gas turbine or a steam turbine capable of restricting an increasing of a secondary flow under a condition in which a strong secondary flow progresses near its end wall.SOLUTION: A turbine comprises: a turbine blade (12) having a pressure surface (10b) and a negative pressure surface (10a) oppositely facing against the pressure surface (10b) and extending from its inner peripheral end wall, and one through-pass flow passage (45) arranged at the inner peripheral end wall (10) at the turbine blade (12) and communicating between the pressure surface (10b) and the negative pressure surface (10a), and a blade shape of the turbine blade including the through-pass flow passage (45) is formed by two blade shapes (36, 37). |
