A condenser includes heat transfer pipe groups, a main body and an intermediate body. The intermediate body has an inlet that opens in a horizontal direction, and an outlet that opens downward. The main body has an inlet that opens upward and is connected to the intermediate body outlet. The heat transfer pipe groups are arranged in the horizontal direction and disposed in the main body. A near-side outlet edge is an edge of the intermediate body outlet on a side near the intermediate body inlet in the horizontal direction and a far-side outlet edge is an edge of the intermediate body outlet on a side far from the intermediate body inlet. At least one part of the main body is located below an imaginary line that connects the near-side and far-side outlet edges and at least one part of the main body is located above the imaginary line.
