PROBLEM TO BE SOLVED: To provide a negative electrode for a secondary battery having a high capacity and excellent cycle characteristics, a method for manufacturing the same, and a secondary battery.SOLUTION: A negative electrode for a secondary battery includes an active material layer 1 that is a sintered body containing a carbonaceous material 1b and particles 1a of an active material; and a collector 3 containing a conductive material. The active material is Si or a Si-containing compound, and an intervening layer 2 made of a carbonaceous material 2b is provided between the active material layer 1 and the collector 3. Thus mutual diffusion and a reaction between Si in the particles of the active material and a metallic element in the conductive material contained in the collector 3 are suppressed to reduce the formation of a reaction product with a low capacity in the active material layer 1. |
