PROBLEM TO BE SOLVED: To provide a bent duct that can control duct loss by wake. SOLUTION: In a bent duct 10 of a gas turbine engine, a plate-like member 16 that has an airfoil shape at cross section is placed on a part where a passage area becomes bigger toward the direction in which fluid runs. The plate-like member 16 that has an airfoil shape at cross section has a ring-like shape as a whole, is mounted within the duct through a strut that is placed between a duct inner circumferential wall and a duct outer circumferential wall and prevents deviations of the pressure distribution within the duct.
