1. An outdoor unit comprising:
a housing;
a compressor placed in the housing;
a heat exchanger placed in the housing;
a blower placed in the housing, the blower admitting air from outside the housing and passing the air through the heat exchanger;
a partition plate partitioning the housing into a compressor chamber and a blower chamber, the compressor being placed in the compressor chamber, the blower being placed in the blower chamber;
a board on which an electronic component is mounted, the electronic component driving the compressor;
a heat dissipator placed in the blower chamber and adjacent to the partition plate, the heat dissipator including a base and a plurality of fins, the base having a fin formation surface, the fins projecting from the fin formation surface, the heat dissipator dissipating heat of the electronic component; and
a duct covering a tip side of the fins in the heat dissipator to form a flow path, the air passing through the flow path, wherein
when the fins are viewed from the fin formation surface side, the fins extend toward the blower side from the partition plate side, wherein
the duct has a facing surface facing the fin formation surface,
a distance between the facing surface and the fin formation surface is greater in a region on the partition plate side than in a region on the blower side, and
an outlet is formed on the blower side of the duct, the outlet allowing the air to flow out from the flow path.
