PROBLEM TO BE SOLVED: To provide an electrode welding-joining device of a lithium ion secondary battery capable of providing a high-performance lithium ion secondary battery. SOLUTION: The electrode welding-joining device comprises: a rotary table 10; a plurality of tools 11 mounted radially from the center of the rotary table and each used for mounting a semifinished product of the lithium ion secondary battery comprising an electrode body and a cap body; an electrode body supply mechanism installed so as to supply the electrode bodies to the tools; a cap body supply mechanism 21a installed so as to supply the cap bodies to the tools; a pair of side face grippers 15a and 15b for detachably gripping the electrode bodies respectively mounted on the tools so as to catch them from their side faces; a plurality of negative electrode welding mechanisms 23 installed so as to weld a negative electrode tab of the electrode body gripped by the side face grippers; a plurality of positive electrode joining mechanisms 24 installed so as to join a positive electrode tab of the electrode body gripped by the side face grippers; and a semifinished product discharging mechanism for discharging the semifinished product from the tool.
