Disclosed is a negative electrode (10) for lithium secondary batteries, which comprises a collector (11) having a plurality of projections (11a) on the surface, a first active material layer (12) formed on the collector (11), and a second active material layer (15) arranged on top of the first active material layer (12) and containing a plurality of active material particles (14). Each of the active material particles (14) is on a corresponding projection (11a) of the collector (11). The first active material layer (12) and the active material particles (14) respectively have a chemical composition represented by SiOx (0 < x < 1). |
