<p>In a nonaqueous electrolyte secondary cell comprising a rolled-up electrode unit (4) encased in a cell can (1), a striplike current collector forming an electrode has an edge (48) projecting from at least one of opposite ends of the electrode unit. The positive electrode (41) and the negative electrode (43) each comprise a striplike current collector and an active substance coating the current collector, each of the electrodes having a portion coated with the active substance and extending longitudinally of the current collector, and an uncoated portion not coated with the active substance and formed along an edge of the current collector, the uncoated portion projecting from at least one of axially opposite ends of the rolled-up electrode unit (4) to provide a cylindrical projection (40), the cylindrical projection (40) being covered with a current collecting plate (6) made of metal, the current collecting plate (6) comprising a top plate (61) in contact with an end face of the cylindrical projection (40) and a skirt portion (62) in contact with at least a portion of an outer peripheral surface of the cylindrical projection (40), the current collecting plate (6) being connected to one of the electrode terminal portions by a lead member (63).</p> |
