An object of the present invention is to provide a sealed battery capable of exhibiting excellent battery performance by reliably welding an electrode terminal and a current collecting component, and a method of manufacturing the same.n n n The main body portion 181 having the disk-shaped terminal portion 180, the hollow portion 185 communicating with the outside at the tip portion 187, and the insertion through hole of the current collector component 22. The formed truncated cone part (cocking covering area | region) 182 is comprised. The bottom surface C of the truncated cone part 182 is crimped and crimped so that the bottom surface C of the conical part 182 may contact with the main surface part B below. The truncated cone portion 182 and the current collector component 22 are laser-welded so that a plurality of welding spot portions 183 are formed in the peripheral region of the truncated cone portion 182.n n n n Negative Terminal, Terminal, Tip, Hollow, Body, and Cone |
