<p>A storage element (1) comprising a storage part in which electric energy is stored and a case (9) in which the storage part is held. The case (9) comprises: a frame (10) having two edge faces (15, 16) having an opening; and a pair of laminated films (50, 60) applied respectively to the two edge faces (15, 16) of the frame (10) to form a storage chamber (49) inside the frame (10). The laminated films (50, 60) comprise application parts (52, 53, 54, 62, 63, 64) applied to the frame (10) and film parts (51, 61) which face the storage chamber (49). Since the laminated films (50, 60), which have not undergone press forming, are applied to the frame (10), no structurally weak region is formed in the laminated films (50, 60). The case (9) hence has improved durability.</p> |
