    • By combining crimping fixing and laser welding, a collector attached to a substrate of an electrode assembly is fixed to a terminal. A negative electrode terminal 19A has a terminal portion formed on one side of a flange portion, and a cylindrical crimping member 19b on the other side. The cylindrical crimping member 19b is inserted through openings formed in a first insulating member, a sealing plate, a second insulating member, and a negative electrode collector 18a. The cylindrical crimping member 19b is crimped in a diameter-increasing direction, and is mechanically fixed in a countersunk hole 18c of the negative electrode collector 18a. A peripheral portion of a thin-walled portion 19d having a thickness smaller than those of other portions formed at the tip end portion of the cylindrical crimping member 19b is thoroughly adhered and welded by a high energy beam to the edge of the countersunk hole 18c.
    • 通过组合压接固定和激光焊接,将附接到电极组件的基板的集电体固定到端子。 负极端子19A具有形成在凸缘部分的一侧上的端子部分和另一侧的圆柱形压接部件19b。 圆柱形压接构件19b通过形成在第一绝缘构件,密封板,第二绝缘构件和负极集电体18a中的开口插入。 圆筒状压接构件19b在直径增大方向上卷曲,并机械地固定在负极集电体18a的埋头孔18c中。 薄壁部分19d的周边部分的厚度小于形成在圆筒形压接部件19b的顶端部分的其它部分的厚度,其周边部分通过高能量光束被充分地粘合并焊接到埋头孔18c的边缘。
