PURPOSE: To realize a battery in which an electrode body can be efficiently received in a battery can by laminating an electrode layer including its folded part in a uniform thickness. CONSTITUTION: An electrode body 1 is formed by folding in a multi-folded layer form an electrode layer 9 in which a positive electrode 4 with a positive electrode active material 3 made to adhere to a positive electrode collector 2 and a negative electrode 7 with a negative active material 6 made to adhere to a negative electrode collector 5 are opposed through a separator 8. A region 10 in which an active material does not exist is provided by intermittently applying a positive electrode active material to the positive electrode collector 2 is adopted as a folded part 9a of the electrode layer 9. |
