Zusammenfassung:A negative electrode for secondary battery includes a negative electrode current collector; a first active material layer in which a first negative electrode slurry containing a first negative electrode active material is coated onto the negative electrode current collector; and a second active material layer in which a second negative electrode slurry containing a second negative electrode active material is coated onto the first active material layer, wherein the first negative electrode active material contains natural graphite having an mesopore volume of 0.6*10−3 cm3/g or more and 2.5*10−3 cm3/g or less, and the second negative electrode active material contains artificial graphite.
