| description | PROBLEM TO BE SOLVED: To provide an electricity storage element capable of suppressing a decrease in output even after a long-term of neglect.SOLUTION: An electricity storage element includes a negative electrode having an active material layer. The active material layer contains particle-like non-graphitizable carbon, as an active material. Pores are formed between the non-graphitizable carbon, in the active material layer. The average particle diameter D50 of the non-graphitizable carbon is 2-10 μm. When the average particle diameter D50 is denoted as x μm and the porosity of the active material layer is denoted as y%, x and y satisfy a relational expression: y≤0.77x+33.23.SELECTED DRAWING: None
