Zusammenfassung:	A lead tab for a secondary battery may include a metal plate and a plurality of concavo-convex patterns formed on a surface of the metal plate. The plurality of concavo-convex patterns may be formed through a surface treatment of applying predetermined laser light energy onto the surface of the metal plate. The external energy may have an output value decided on the basis of the material of the metal plate, and the surface of the metal plate may be treated with the decided output value.
