NOVELTY - The non-aqueous electrolyte battery (10) has a cell layer(s) (19) having sequential lamination of an anode active material layer (13), an electrolyte layer (17) containing a non-aqueous electrolyte and a cathode active material layer (15). The ratio of solid content of active material layer(s) with respect to total active material layer product is 50 volume% or less. The smoothing rate of active material layers surface is 50% or more derived from surface area of active material layer surface at a preset depth and total surface area of active material layer.    USE - For e.g. bipolar type lithium ion secondary cell used for vehicle (both claimed) such as fuel cell electric vehicle and hybrid vehicle.    ADVANTAGE - The non-aqueous electrolyte battery has improved energy density and output characteristics. The battery is manufactured with high yield. The short circuit of anode active material and/or cathode active material interlayer is prevented.    DETAILED DESCRIPTION - The non-aqueous electrolyte battery (10) has a cell layer(s) (19) having sequential lamination of an anode active material layer (13), an electrolyte layer (17) containing a non-aqueous electrolyte, and a cathode active material layer (15). The anode active material layer contains an anode active material, and is formed on surface of a collector (11). The cathode active material layer contains a cathode active material, and is formed on surface of collector. The ratio of solid content of active material layer(s) with respect to total active material layer product is 50 volume% or less. The smoothing rate of active material layers surface is 50% or more derived from relation: (surface area of active material layer surface at a depth of (average particle diameterx1/2)/total surface area of active material layer)x100.    INDEPENDENT CLAIMS are included for the following:    (1) battery pack;    (2) vehicle; and    (3) manufacture of non-aqueous electrolyte battery electrode.
