A sealed battery terminal 18 of a first aspect of the invention includes an electrically-conductive terminal cap 19, a rupture disk 25 made of flexible electrically conductive material electrically connected to the electrically-conductive terminal cap 19, and an electrically-conductive terminal plate 20 abutting the rupture disk 25. In the sealed battery terminal 18, an opening 23c is formed in the terminal plate 20, the rupture disk 25 is arranged to close the opening 23c, and an abutting part of an inner periphery of the opening of the terminal plate 20 and the rupture disk 25 is welded by a high energy beam at a plurality of places. Accordingly, a sealed battery terminal having a safety valve system in which the rupture disk placed in the cap and the terminal plate are electrically connected directly by welding with the high energy beam can be provided. |
