  "textContent": "A nonaqueous electrolyte secondary battery (100) includes: a negative electrode current collector foil (21); and a negative electrode mixture layer (22) that is arranged on the negative electrode current collector foil. The negative electrode mixture layer contains a plurality of granulated particles. Each of the granulated particles contains a negative electrode active material (2) and a coating film (4). The coating film is formed on a surface of the negative electrode active material. The coating film includes a first film (4a) and a second film (4b). The first film is formed on the surface of the negative electrode active material. The second film is formed on the first film. The first film contains a carboxymethyl cellulose polymer. The second film contains a polyacrylic acid polymer.",
