PROBLEM TO BE SOLVED: To provide a condenser which is improved in safety and reliability by improving the cooling performance of the condenser by remedying the flowing mode of a steam flow in the condenser and, at the same time, reducing the size of the condenser by reducing the height of the condenser and preventing the occurrence of a failure, such as the water leakage, etc., in the air extracting section of the condenser. SOLUTION: In a condenser which condenses steam by cooling the steam by means of a cooling pipe group laid in an outer shell 1 of the condenser, the pipe group is divided into an upper pipe subgroup 21 laid above a horizontal tray and a lower pipe subgroup 22 laid below the tray 6 and the lateral outline shape of the subgroup 21 is tapered in such a way that the width of the subgroup 21 becomes narrower as going upward from the tray 6. In addition, the side contour shape of the subgroup 22 is formed in such a way that the width of the subgroup 22 becomes the narrowest at, at least, the bottom end of the subgroup 22. In addition, a vertical air moving passage 4 is provided through the upper and lower pipe subgroups 21 and 22.
