PROBLEM TO BE SOLVED: To provide a welding method of a battery container having larger welding intensity to a lead material even with low welding current and having less variations when a lead material is welded by a parallel type resistance welding method. SOLUTION: In the welding method of a battery container, a lead material arranged on a surface of a plating layer of a battery container with a coating layer made of an Ni base alloy formed on a part or a whole of an outside surface, the lead material is pressed with a welding pressure of 22N by two welding electrodes, a parallel type resistance welding is proceeded by a welding current of 1.2kA to 1.6kA, and the lead material is welded to the battery container with a welding intensity of 53.5 to 75.3N.
