    摘要: The present invention provides a secondary cell having a rolled-up electrode unit accommodated into an outer body. While an uncoated portion of a positive electrode projects at one of axially opposite ends of the rolled-up electrode unit to form a projection, an uncoated portion of a negative electrode projects at the other end to form a projection. Each of the two projections is formed with a current collecting auxiliary portion obtained by bringing each pair of the uncoated portions into ultrasonic pressing contact with each other. An electrode tab is attached to each of the positive electrode and the negative electrode. Outer ends of the two electrode tabs project outward beyond the outer body. The two outer ends provide a pair of positive and negative electrode terminal portions.
