Along with this, there is a growing demand for an improvement in the energy density of the battery, and there is a demand for a lighter and thinner battery case. In addition, diversification of the shape is progressing, and improvement in moldability is expected. BACKGROUND ART A simple case of aluminum is used for a packaging case of a unit cell constituting a conventional battery. However, metal battery cases are heavy and thick. In addition, metal battery cases are hard and difficult to form into various shapes. On the other hand, it was also difficult to manufacture a battery case with a single plastic film due to the problems of the barrier properties of the electrolytic solution and moisture proofness against moisture.
