Electroe constituent member for battery module

An electrode constituent member for a battery module, forming an electrode of the battery module formed by housing an electricity-storage cell in a case, comprising:

• a current-carrying member including an internal connection portion electrically connected to the electricity-storage cell, and an external connection portion exposed to an outside of the case;
• a fastener member passing through a through hole formed in the external connection portion of the current-carrying member from an inner side of the case so as to protrude one portion to the outside of the case, and by the protruded one portion, fastening a member electrically connecting electrodes of a plurality of battery modules;
• and
• an insulating member positioned between the fastener member and the electricity-storage cell,
• wherein the external connection portion is formed with a pair of clamp portions, extending to the inner side of the case and receiving the insulating member in between, and
• the clamp portions and the insulating member respectively are formed with engagement portions engaging with each other when the insulating member is received.
