PROBLEM TO BE SOLVED: To resolve a problem that, because any of conventional methods of manufacturing a negative electrode for a nonaqueous electrolyte secondary battery use a so-called semiconductor manufacturing method, such as photolithography or sputtering, although a method of manufacturing the nonaqueous electrolyte secondary battery for a general-purpose item with ease at low cost is strongly desired, cost of the manufacture consequently becomes high in these conventional methods of manufacturing the negative electrode for the nonaqueous electrolyte secondary battery.SOLUTION: A method of manufacturing a negative electrode for a nonaqueous electrolyte secondary battery forms a negative electrode active material film 8a configured by a negative electrode active material 7 and having a fine uneven pattern, on a base material 1. The method includes: a first step of making a surface roughness in a surface uneven part 5 to be larger than a surface roughness of a portion of a surface of the base material 1 where a recess of the uneven pattern is to be formed; and a second step of supplying the negative electrode active material 7 onto the base material 1 to form the negative electrode active material film 8a. |
