Abstract: A secondary battery of the present invention includes a battery element that includes a positive electrode and a negative electrode, a plurality of metal terminals that are connected to the positive electrode and the negative electrode, the metal terminals each having an outer peripheral surface provided with a resin film, and includes a lamination of at least a metal foil layer and a heat-sealable resin layer made of a polyolefin resin. A first package sealed portion, a second package sealed portion and a film sealed portion are each formed by pressing and heat sealing so as to have a thickness smaller than that of the peripheral region. The film sealed portion has a specific heat of fusion measured according to JIS K 7122 greater than that of a portion of the resin film other than the film sealed portion.
