Abstract: A battery includes an external terminal member and an insulating member on an outer surface of a lid member so that an interval between the insulating member and the lid member is smaller in a long side of the lid member than in a short side. A weld mark is formed over the entire circumference of the lid member to extend across the outer surface of the lid member and an open end face of the case body. The weld mark not only extends across the outer surface of the lid member and the open end face of the case body but also reaches an outer side surface of the case body in a zone of the long side of the lid member facing the insulating member, but does not reach the outer side surface of the case body in a zone except the former zone.

Abstract translation: 电池在盖构件的外表面上包括外部端子构件和绝缘构件，使得绝缘构件和盖构件之间的间隔在盖构件的长边比在短边中更小。 在盖构件的整个圆周上形成焊接标记，以延伸越过盖构件的外表面和壳体的开口端面。 焊接标记不仅延伸穿过盖构件的外表面和壳体的开口端面，而且还在盖构件的面向绝缘构件的长边的区域中到达壳体的外侧表面， 但是在除了前一区域之外的区域中没有到达壳体的外侧表面。

Abstract: A battery houses an electrode body inside a battery case including a bottomed cylindrical case body having an opening part, and a plate-like lid member inserted in the opening part so as to seal the opening. The opening part and a lid peripheral edge part are welded hermetically by an energy beam irradiated from outside in the thickness direction of the lid member. In a specific section, the inner peripheral surface of the opening part and the peripheral edge surface of the lid peripheral edge part are welded in close contact with each other. A bead at the specific section takes a fan shape having a central angle of 160 to 200 degrees in a cross section, and the center of the fan shape is positioned on the inner peripheral surface and the peripheral edge surface.
Abstract translation: 电池容纳电池壳体内的电极体，该电池壳体包括具有开口部的有底筒状壳体，以及插入该开口部的密封开口部的板状盖构件。 开口部和盖周缘部通过从盖部件的厚度方向的外侧照射的能量束气密地焊接。 在特定部分中，开口部的内周面和盖周缘部的周缘面彼此紧密焊接。 特定部分的珠子在横截面中具有中心角为160至200度的扇形，并且扇形的中心位于内周表面和周边边缘表面上。
