Kind Code:
A1
Abstract:
A method for manufacturing an electrode lead, according to an embodiment of the present invention for addressing an issue, comprises the steps of: manufacturing a first electrode lead and a second electrode lead, respectively; and forming a connection part by adhering the first electrode lead and the second electrode lead to each other. The step of manufacturing the first electrode lead comprises the steps of: unwinding a first metal plate from a first metal reel; on the first metal plate, attaching, for masking, a first tape to a first connection region where the connection part is to be formed; performing plating and surface-treatment processes on the first metal plate; and removing the first tape. The step of manufacturing the second electrode lead comprises the steps of: unwinding a second metal plate from a second metal reel; on the second metal plate, attaching, for masking, a second tape to a second connection region where the connection part is to be formed; performing plating and surface-treatment processes on the second metal plate; and removing the second tape.
