An air-conditioning apparatus includes a heat-exchange unit. The heat-exchange unit has a pair of heat exchangers, and a partition plate disposed in such a state that a first region located on the inside of a space between the pair of heat exchangers and a second region located on the outside of the space are formed. The heat-exchange unit is disposed in such an orientation that one of the pair of heat exchangers is provided adjacent to and above the other heat exchanger and that the second region of the partition plate is located on the downstream side of the first region. The second region of the partition plate is provided with an inlet of a drain path.
