Abstract
A battery pack includes a plurality of prismatic batteries including an electrode plate group and electrolyte housed in a prismatic battery case and being arranged in parallel and integrally bound. A metal plate is integrally embedded in the sidewall of the prismatic battery which is in parallel with the electrode plate group. A heat transfer part protruding from the prismatic battery case is provided at least one side of the metal plate. A heat exchanger is provided such that a heat exchanging surface of the heat exchanger is brought into contact with the heat transfer part protruding from the prismatic battery case of the prismatic battery. Then, the battery pack and the heat exchanger are fixed.
