PROBLEM TO BE SOLVED: To provide a novel structure for fixing (connecting) a busbar to an electrode terminal. SOLUTION: The battery pack is structured of a plurality of unit batteries 10, electrically connected with each other, each 10 provided with a battery case housing an electrode body and an electrode terminal 62 protruded toward an outside face of the case. Between two adjacent unit batteries 10 among the plurality of them, one electrode terminal 62 and the other electrode terminal are coupled with each other through the busbar 20. The busbar 20 is a metal member having a platy body for connecting between electrodes and is quipped with a terminal insertion part 22 for the electrode terminal 62 to be inserted into, and a pawl part 26, constituting at least a part of the peripheral edge of the terminal insertion hole 22, and formed to be slanted from a body part 24 of the busbar toward a tip-end direction of the electrode terminal 62, so that the busbar 20 is fixed to the electrode terminal 62 as the pawl part 26 is caulked to the electrode terminal 62 inserted into the terminal insertion hole 22.
