Zusammenfassung:	Disclosed are a weld portion inspection method using thermal image sensing, and more particularly a method of inspecting a weld portion between a lead portion of a battery cell and a busbar, wherein the weld portion (300) is heated using Joule heat and whether the weld portion (300) is defective is determined based on a temperature increase change of the weld portion (300).
