Abstract
This stationary blade segment includes a first stationary blade, a second stationary blade, and a connecting implement that connects the first stationary blade and the second stationary blade. A first shroud of the first stationary blade includes a first gas path face, and a first protruding part that protrudes to a reverse-channel side at a first end section of the first shroud. A second shroud of the second stationary blade includes a second gas path face, a second protruding part that protrudes to the reverse-channel side at a first end section of the second shroud, and a third protruding part that protrudes to the reverse-channel side at a second end section of the second shroud and that is connected to the first protruding part by the connecting implement.
