A package-type fluid machine includes a compressor unit including a compression portion that compresses a fluid, a motor that drives the compression portion, and a cooling fan that is driven by the motor; a machine chamber in which the compressor unit is disposed; an inverter chamber which is adjacent to the machine chamber and in which an inverter is disposed; a partition wall that partitions off the machine chamber from the inverter chamber and has an opening; and an inverter intake port that is disposed in the inverter chamber to take in a cooling gas. The cooling fan is disposed on a side of the machine chamber, the opening being located on the side. The cooling fan is driven to cause the cooling gas to flow from the inverter intake port to the opening to cool the inverter.
