    摘要： A negative electrode (10) for use in a non-aqueous electrolyte secondary battery comprises an active material layer (12) containing a particle (12a) of an active material. At least a part of the surface of the particle (12a) is coated with a metal material (13) having a poor ability of forming a lithium compound. A void is formed between the particles (12a) that are coated with the metal material (13). The active material layer has a void ratio of 15 to 45%. Preferably, the metal material (13) is present over the entire area of such a part of the surface of the particle that extends in the thickness-wise direction of the active material layer. Also preferably, the particle (12a) of the active material is composed of a silicone material, and the active material layer (12) contains a conductive carbon material in an amount of 1 to 3% by weight relative to the weight amount of the particle (12a) of the active material.
