An electrical component disposed on the top of battery modules includes an electrical component case for accommodating an inverter and a DC/DC converter, and heat sink units attached to the electrical component case on the side of the electrical component case opposite to the side with the battery modules, and constituted of a heat radiating plate having a plurality of radiating fins. In addition, a cooling path has a first cooling path for cooling the battery modules using cooling wind, and a second cooling path for cooling the heat sink units using the cooling wind having passed through the first cooling path. With this arrangement, there is provided a cooling structure for a vehicle power source unit capable of cooling the battery and the electrical component including the inverter with a compact configuration.
