A structure of a hybrid vehicle includes a battery pack arranged on a floor panel and an exhaust pipe extending from an engine, passing below the floor panel, to an exhaust port. The battery pack has a secondary battery constituted by a plurality of battery cells stacked in a vehicle traveling direction for supplying electric power to a motor, and an intake chamber provided adjacent to the secondary battery in a substantially horizontal direction perpendicular to the direction along which the plurality of battery cells are stacked for supplying cooling air between each of the plurality of battery cells. The exhaust pipe is provided so that it passes immediately below the battery pack and passes a position displaced from a position immediately below the intake chamber. With such a configuration, a structure of a hybrid vehicle that suppresses reduction in the efficiency of cooling a secondary battery without placing a great limit on routing of an exhaust pipe is provided.
