    摘要： The present invention relates to a lithium ion battery employed by connecting the positive electrode side to a negative electrode portion made of Cu or a Cu alloy by a bus bar made of Al or an Al alloy and provides a negative electrode terminal for a lithium ion battery capable of providing sufficient bonding strength between the negative electrode portion and the bus bar when the negative electrode portion and the bus bar are metallurgically bonded to each other by resistance welding or the like, for example. This negative electrode terminal for a lithium ion battery is made of a clad material having a first metal layer made of Al or an Al alloy and a second metal layer made of Cu or a Cu alloy bonded to each other through a reaction-suppressing layer suppressing a reaction therebetween.
