摘要：
A negative electrode 100 for a nonaqueous electrolytic secondary cell includes a current collector 1 and a plurality of active material bodies 2 formed on a surface of the current collector 1 at intervals; each active material body 2 contains a material for occluding or releasing lithium; and a plurality of projections 3 are formed on a part of a side surface of each active material body 2.
