    摘要: A secondary battery capable of obtaining superior cycle characteristics and superior swollenness characteristics is provided. The secondary battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. An anode active material layer contains a crystalline anode active material having silicon as an element. The anode active material layer has a coating section where the surface of an anode current collector is coated with the anode active material and a non-coating section where the surface of the anode current collector is not coated with the anode active material but is exposed. Thereby, the physical property of the anode active material is hardly deteriorated with age. Further, at the time of charge and discharge, the anode active material layer is hardly expanded and shrunk, and thus the anode current collector is hardly deformed.
