A condenseris disposed under a steam turbineincluding a downward exhaust-type exhaust chamber. The condenserincludes: a condenser main body part; a connecting body partconnecting the exhaust chamberand the condenser main body partand having a pair of lateral sidewallswhose inner wall surfacesare inclined more outward in terms of the perpendicular direction as they go more downstream; and a pair of plate-shaped memberswhich are provided on inner wall surfacesof longitudinal sidewallsthe pair of plate-shaped membersbeing located across a position of an inletof the connecting body partand on more outer sides than the position of the inletin terms of the perpendicular direction, projecting in the turbine rotor axial direction, and extending downstream.
