PROBLEM TO BE SOLVED: To inhibit the deposition of dendrite regardless of type of an electrode material in a secondary battery.SOLUTION: A secondary battery includes: a first electrode 1; and a second electrode 2 that is disposed facing the first electrode 1 and has a surface area larger than a facing surface of the first electrode 1. Further, an electrolytic solution 4 including at least metal ions is disposed between the first electrode 1 and the second electrode 2. Further, the secondary battery includes position change means 7,9 changing a position of a facing surface of the second electrode 2 relative to the first electrode 1. |
