To provide an outdoor unit, in which low-cost and effective heat exhaust action can be obtained without especially installing a dedicated heat dissipation means separately, and the size of a housing is not increased.
The outdoor unit includes a fan chamber A with an evaporator 10 and a fan F for cooling the same, in a housing 31, a machine chamber B housing at least a compressor 4 and an accumulator 3, an electric equipment chamber C housing various electric components including an inverter 11 disposed in an upper space on the upper side of the machine chamber B through a chassis 42 and controlling actuation of the compressor 4, and is configured such that the machine chamber B and the electric equipment chamber C and the fan chamber C are separated to right and left by a partition plate 41, and when external air is taken from an external air suction hole 35B opened to an accumulator 3 opposing area of a back surface plate 35 of the housing 31, the external air is cooled, and after allowing the external air to finally pass through the inverter 11 at the most depth part in the electric equipment chamber C, the external air is let out to the fan chamber A through a rainproof exhaust part 50 provided to the partition plate 41.
