PROBLEM TO BE SOLVED: To provide a condenser capable of reducing a resistance against a steam flow of an upper side tube bundle even when a temperature difference between the steam and cooling water is reduced due to the tube bundle and assuring high condensing performance in all tube bundles in a two-folding flow type condenser for introducing the water from a lower part. SOLUTION: In the two-folding flow type condenser comprising a tube bundle 1 having a plurality of cooling tubes densely gathered and arranged and vertically split to supply cooling water to its lower tube bundle 1a and to discharge the water from its upper tube bundle 1b, a steam inlet 40 is disposed above the tube bundle, a tube bundle width of the tube 1b is increased toward downward, a tube bundle width of an upper end of the lower tube bundle 1a is a width or below of a lower end of the upper tube bundle 1b, and a tube bundle width of the lower tube bundle 1a becomes a maximum between the upper and the lower end.
