Abstract: A power source apparatus includes a battery module including a plurality of battery cells, a housing forming a housing chamber to house and arrange a plurality of the battery modules in parallel, a blower to blow air, an inter-module path formed between the battery modules adjacent to each other; and an inter-cell path formed between the battery cells adjacent to each other. The housing includes an intake portion to take the air into the housing chamber, and a sending portion to send the air from the housing chamber. The inter-module path has a first inter-module path serving as a path into which the air is introduced. The sending portion is separated, adjacent to at least one battery module, from the first inter-module path such that the air flows in the inter-cell paths of a plurality of the battery modules arranged next to the first inter-module path and adjacent each other.
