PROBLEM TO BE SOLVED: To provide a bus bar which makes a liquid leaked from a battery less likely to be transmitted to an external conductor.SOLUTION: A bus bar 8 is formed into a plate shape. One main surface 8a of the bus bar 8 faces first and second batteries 2b, 2c having a liquid therein and the other main surface 8b contacts with a terminal 9. The bus bar 8 includes: a first insertion hole 14; a second insertion hole 15, and a liquid retention part 21. A first electrode 6a included in the first battery 2b is inserted into the first insertion hole 14. A second electrode 6b included in the second battery 2c located adjacent to the first battery 2b is inserted into the second insertion hole 15. The liquid retention part 21 is provided at a position separated from the first insertion hole 14 and is formed into a cylindrical shape that has openings 19, 20 at upper and lower portions thereof. The bus bar 8 is provided so as to be sandwiched between the terminal 9 having an electric wire connection part 23 with which an electric wire 25, electrically connecting the first electrode 6a with the exterior, is connected and each battery 2b, 2c and serially connects the batteries 2b, 2c with each other. |
