摘要：
In a welding method, at least one of a set of a first electrode collector and a first terminal and a set of second electrode collector and a second terminal is welded one another. At this time, a laser beam is irradiated to a portion to be welded, elastic waves generated due to the laser beam from the portion to be welded are detected, and the detected elastic waves are integrated to calculate an index corresponding to an amount of connection energy in order to check a welded state.
