    摘要: An electrical storage unit includes an electrical storage section whose collector-exposed portion formed on both ends of an element is attached to a terminal plate or an outer case, and a pair of cooling plates making contact with an outer surface of the terminal plate or an outer bottom face of the outer case of the electrical storage section. This enables heat release from the electrical storage section to the cooling plate via a material with high heat conductivity, such as a metal member. Accordingly, the electrical storage section heated in charge and discharge cycles can be efficiently cooled.
