An air-conditioning apparatus includes a compressor and an outdoor heat exchanger that operates as an evaporator. A first heat exchange unit of the outdoor heat exchanger includes: first heat transfer tubes extending in an upward/downward direction, and arranged apart from each other in a lateral direction; a first junction pipe extending in the lateral direction, and connected to the lower ends of the first heat transfer tubes; an outflow pipe connected to the first junction pipe at or below a center position of the first junction pipe in the upward/downward direction; second heat transfer tubes extending in the upward/downward direction, and arranged apart from each other in the lateral direction; a first distribution pipe extending in the lateral direction, and connected to the lower ends of the second heat transfer tubes, and a first connection part connecting upper ends of the first heat transfer tubes and upper ends of the second heat transfer tubes.
