<P>PROBLEM TO BE SOLVED: To provide an electrode plate for a nonaqueous secondary battery, in which: sagging is suppressed which occurs on an end face of the electrode mixture layer of the nonaqueous secondary battery electrode plate when the electrode mixture coating is continuously or intermittently applied on the surface of a current collector, dried and rolled to form the electrode mixture layer; decrease of an ion reaction area can be prevented; and a utilization rate of the electrode mixture layer is improved. <P>SOLUTION: A water-repellent material 16 is applied to the current collector 1 at positions corresponding to the electrode mixture layer 2 formed with the electrode mixture coating and the uncoated parts 19 of the electrode mixture coating so that the saggings occurring on the end faces of the electrode mixture layer 2 of the nonaqueous secondary battery electrode plate are suppressed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
