1. An indoor unit of an air-conditioning apparatus, comprising:
a fan including a rotating shaft that extends in a lateral direction in a housing;
a heat exchanger provided in the housing and upstream of the fan in an air passage; and
a drain receiver configured to receive water at a position close to a lower end of the heat exchanger, the water being generated in the housing,
wherein an interior of the housing is partitioned into a first space and a second space in an axial direction of the rotating shaft of the fan, the first space being a space in which a first opening is provided to allow air to flow out toward a region located outward of the fan in the first space in a radial direction of the fan, the second space being a space in which no opening is provided and a region located outward of the fan in the second space in the radial direction of the fan is closed,
in at least part of a space between the fan and the heat exchanger in the first space, a first water receiving device is provided at a higher position than the drain receiver, and
in a space between the fan and the heat exchanger in the second space, a second water receiving device having a surface area smaller than a surface area of the first water receiving device in the first space is provided, or the second water receiving device is not provided and an air passage corresponding to the surface area of the first water receiving device in the first space is provided.
