Document Type and Number:
WIPO Patent Application WO/2012/011361
Kind Code:
Disclosed is an electrochemical device wherein there is no degradation of characteristics as a result of a step in which a rigid case and a conductive lid are joined together. A weld section (PP) of the conductive lid (12) and a weld frame (11d) on the rigid case (11) are joined to each other by laser welding. A weld bead (50) that joins said weld section (PP) and weld frame (11d) is not exposed to a space inside a rigid package (10), thus preventing meltage, solidified meltage, or the like produced during laser welding from getting inside said rigid package (10).
