Abstract
A nonaqueous electrolyte battery includes an electrode group and a nonaqueous electrolyte. The electrode group has a laminated structure in which positive electrodes and negative electrodes are alternately interposed between overlapped parts of a separator folded in a zigzag form. A Gurley value of an outermost layer of the separator is larger than that of an inner layer. The battery satisfyies the following equation (1):3×10−5≦(X/Y)≦1.5×10−3 (1)wherein X is a rated resistance [mΩ] of the nonaqueous electrolyte battery and Y is a rated capacity [mAh] of the nonaqueous electrolyte battery.
