Abstract
A turbine blade includes a blade main body that includes a cooling flow path formed inside, through which a cooling medium flows; and a plurality of turbulators that are aligned in a flow direction of the cooling medium, project into the cooling flow path from an inner surface of the blade main body, and extend in a direction intersecting with the flow direction. At least one of the turbulators is a first turbulator. The first turbulator includes a first portion and a second portion. The first portion is connected to the first portion and has a projecting height from the inner surface that changes at a first change ratio along a direction intersecting with the flow direction. The second portion has a projecting height from the inner surface that changes at a second change ratio higher than the first change ratio along the direction intersecting with the flow direction.
