  "textContent": "The manufacturing method herein disclosed includes a forming step of stacking a positive electrode sheet including a positive electrode active material layer on a positive electrode collector, a negative electrode sheet including a negative electrode active material layer on a negative electrode collector, and a separator sheet, thereby forming an electrode body; a constructing step of accommodating the electrode body in a battery case, and pouring an electrolyte into the battery case, thereby constructing a battery assembly; and a charging step of charging the battery assembly. At least any one of the positive electrode active material layer and the negative electrode active material layer has an undulating shape in a stacking direction, and a pit depth of the undulation is 10 μm or more.",
