Abstract: A negative active material thin film provided on a collector layer directly or via an underlying layer has a multi-layered configuration including at least two silicon thin films containing silicon as a main component. Because of this, even when the thickness of the negative active material thin film is increased, the increase in thickness of one silicon thin film can be prevented by increasing the number of silicon thin films. Thus, the diameter of silicon particles substantially in an inverse truncated cone shape is not enlarged in the silicon thin film. Accordingly, in an energy device having a thin film mainly containing silicon as a negative active material, even when the thickness of the negative active material layer is increased to obtain a larger capacity, cycle characteristics are not degraded.

Abstract: A negative active material thin film containing silicon as a main component is formed on a collector. A composition gradient layer, in which a composition distribution of a main component element of the collector and silicon is varied smoothly, is formed in the vicinity of the interface between the collector and the negative active material thin film. The composition gradient layer contains at least one kind of third element selected from W, Mo, Cr, Co, Fe, Mn, Ni, and P, in addition to the elements contained in the collector and the elements contained in the negative active material thin film. The third element irregularizes the atomic arrangement at the interface between the collector and the negative active material thin film.
