摘要： When a linear welding trace is formed by welding a battery case and an electrode tab, an output of the laser increases to a first output during a first period after laser irradiation start to melt the battery case until the electrode tab is melted with the first output, the first output is maintained during a second period to melt the electrode tab and the battery case, the output of the laser decreases from the first output to a second output for melting only the battery case, and the second output is maintained until formation of the welding trace is completed or the laser output is decreased from the second output by an amount that is less than the decrease amount when the laser output decreased from the first output to the second output.
