A condenser including a steam cooling tube bundle having a number of steam cooling tubes, an enclosure enclosing a central space formed at an inside of the steam cooling tube bundle, an air cooling tube bundle disposed in the enclosure and having a number of air cooling tubes, and a tube support plate supporting the steam cooling tube bundle. The steam cooling tube bundle includes upper and lower tube bundles. The enclosure includes a pair of enclosing bodies dividing the steam cooling tube bundle into two parts. Each of the enclosing bodies includes an upper enclosing plate having at least a sloping surface inclined downward to an outside from an inside of the enclosure and a bottom enclosing plate disposed downward of the upper enclosing plate. A flow opening is formed at a joined portion of upper and bottom enclosing plates to communicate the inner space and the outer space. A drain opening is formed at a joined portion of the bottom enclosing plate positioned at the inner space side and the tube support plate.
