The present invention has an object to provide a non-aqueous electrolyte secondary battery having a high capacity and favorable charge/discharge characteristics at a high current density. In order to achieve this object, the positive electrode for a non-aqueous electrolyte secondary battery in accordance with the present invention includes a current collector and an active material layer, the active material layer has a first active material layer including dendritic active material particle, and the dendritic active material particles branch out into a plurality of branch portions from a bottom portion of the current collector side toward a surface side of the first active material layer. In the first active material layer, it is preferable that an active material density of the bottom portion side is larger than an active material density of the surface side. |
