PROBLEM TO BE SOLVED: To provide a terminal for a battery with high reliability by preventing breakage of a welding part of a terminal member and a current collector, enhancing joint strength and electric continuity between the terminal member and the current collector, and joining the terminal member and the current collector in a accurate dimension and arrangement. SOLUTION: The terminal for the battery is equipped with a columnar terminal member made of aluminum and having a flange part 12a formed at the lower end of an outer circumferential surface over the whole circumference; a cylindrical insulating member 10 made of ceramic through which the terminal member 12 is inserted and joined so that both ends are projected; and an annular member 11 made of metal and joining the inner circumferential surface to the outer circumferential surface of the insulating member 10, and the flange part 12a of the terminal member 12 is formed in a position higher than the lower end of the terminal member 12, and a groove 12b is formed at the inner circumferential end of the lower surface of the flange part 12a over the whole circumference.
