(57) [Summary] [PROBLEMS] To be able to cope with ultra-thinness, to reduce the volume loss, to reliably and easily perform the welding of the power generation element leads and the electrical connection to the external connection terminal plate, and to achieve a stable sealing. Provided is a sealed battery capable of obtaining the stopping performance and electric resistance. A bottomed cylindrical metal outer can (17) and an outer can (1) are provided. 7 and a metal lid 23 joined to the opening of the outer can 17 and to which the connection lead 31 of the power generation element 20 is connected by welding, and one side with respect to the center of the flange 24b. An eccentric solid in which a shaft portion 24a integrally formed at an eccentric position is inserted into the mounting hole 23a of the lid 23, and a connection lead 30 of the power generation element 20 is connected to a portion of the flange portion 24b on the other side by welding. Rivet 24, lower gasket 27 for electrically insulating eccentric solid rivet 24 and lid 23 An external connection terminal plate 29 fixed to the tip of the shaft portion 24a in an electrically connected state; an external connection terminal plate 29; And an upper gasket 28 that electrically insulates the upper gasket. |
