An outdoor unit (20) of an air-conditioning apparatus (1) according to the present embodiment comprises a heat exchanger (25), a floor frame (8), and a cap (14). The heat exchanger (25) is made of aluminum or aluminum alloy. The heat exchanger (25) has a plurality of flat pipes (2) arranged in rows so as to face a side face, a header manifold (6) to which each of the flat pipes (2) is connected, and a plurality of fins (4) joined to the flat pipes (2). In the heat exchanger (25), exchange of heat occurs between a fluid flowing inside the flat pipes (2) and air flowing outside the flat pipes (2). The heat exchanger (25) is mounted on the floor frame (8). The cap (14) covers a lower end part (6a) of the header manifold (6) from below. The cap (14) has a drainage opening (17) through which water that has entered via a gap between the header manifold (6) and the cap (14) drains out. |
