Structure with elements includes a main body of the element used in gas stream and a plurality of fluid passage. Each outlet of the fluid passage is opened on surface of the main body. Coolant fluid flows from each outlet through the passage to cover the surface as a film-like fluid. The plurality of fluid passages include first fluid passages and second fluid passages. The coolant fluid flows from the outlet of the first fluid passage along the direction of the gas stream on the surface. On the other hand, the coolant fluid also flows from the outlet of the second fluid passage toward the gas stream neighbored on each outlet of the first fluid passage.
