PROBLEM TO BE SOLVED: To provide a manufacturing method of a sheet-like plate to obtain a battery which is excellent in safety and has high capacity and on which capacitive dispersion is reduced and whose charge-discharge cycle characteristic is improved in a nonaqueous electrolyte battery having a spiral structure by winding a sheet-like electrode. SOLUTION: In manufacture of this battery composed of a positive electrode, a negative electrode, a separator and an electrolyte, an electrode material applying liquid 7 is delivered from a die nozzle 4, and while arranging unapplied parts 14 at regular intervals in the lengthwise direction on a traveling conductive base material 1, and while continuously changing an applying quantity per unit area, that is, an applying thickness in the lengthwise direction in respective applying parts 15 between the unapplied parts 14, application is performed. Next, pressurizing processing is performed after it is dried. A difference in an applying quantity between lengthwise directional both end parts of the respective applying parts 15 is set at a rate of 2 to 20% with a minimum value as a reference, and therefore, it is desirable that a difference in density of an active material existing in an electrode mix layer after pressurizing processing is also set at a rate of 2 to 20% with the low density side as a reference. |
