  "textContent": "A negative electrode for nonaqueous electrolyte secondary batteries includes a negative electrode current collector and a negative electrode mixture layer disposed on the negative electrode current collector, and the negative electrode mixture layer contains a negative electrode active material containing lithium titanate, a binder, and a (meth)acrylic acid-based polymer. The amount of the (meth)acrylic acid-based polymer in the negative electrode mixture layer is 10 mass % or less relative to the total amount of the (meth)acrylic acid-based polymer and the binder. The amount of the (meth)acrylic acid-based polymer in a portion of the negative electrode mixture layer that extends from the surface to the middle of the negative electrode mixture layer in the thickness direction (upper region) is 60 mass % or more relative to the total amount of the (meth)acrylic acid-based polymer.",
