Abstract
A battery includes an electrode body having a positive electrode and a negative electrode and also includes an exterior case for receiving the electrode body. An insulation film for isolating the exterior case and the electrode body from each other is placed between an inner wall surface of the exterior case and the electrode body. The insulation film has a bag-like shape in which the electrode body is inserted. The bag-like insulation film has a gap filling section on its surface facing a side surface of the electrode body, and the gap filling section closes a gap between the electrode body and the inner wall surface of the exterior case.
