The negative electrode active material-containing layer includes a facing section which faces the positive electrode active material-containing layer and a non-facing section which does not. A first fluorine-containing coating is formed on a main surface of the negative electrode active material-containing layer in at least a part of the non-facing section. The abundance ratio of fluorine atoms included in the first fluorine-containing coating is in the range of 2.5 atom % to 10 atom %.",
