Abstract
A method of joining an electrode lead includes: first stacking a welding metal plate and a tab of a secondary battery; first welding the welding metal plate and the tab stacked with each other at the first stacking, thereby forming a welding intermediate; filling a welding hole formed in the welding intermediate, with a welding material; second stacking the welding intermediate filled with the welding material and a metal lead; and second welding the welding intermediate and the metal lead stacked with each other at the second stacking.
