Beschreibung
Zusammenfassung:	The present invention comprises: an anvil provided so that an overlapping surface of an electrode tab and an electrode lead, which are provided in an electrode assembly, are disposed thereon; a horn configured to weld the overlapping surface disposed on the anvil; and an inspection member configured to inspect a horizontal level of an opposing member with respect to the overlapping surface, based on an overlapping surface horizontal value that is a horizontal value of the overlapping surface with respect to a predetermined reference surface and an opposing horizontal value that is a horizontal value of the opposing member, which is one of a welding part of the horn facing the overlapping surface and a disposing part of the anvil, on which the overlapping surface is disposed, with respect to the predetermined reference surface.
