PROBLEM TO BE SOLVED: To provide a bus bar with which leakage of exhaust gas of a battery from a gas passage is suppressed.SOLUTION: A bus bar 3 is connected with an electrode 50 of a battery 5 and sections a gas passage 23 for discharging exhaust gas from the battery 5 together with an upper case 22. The bus bar 3 has a conductive part 30 composed of a planar conductive material and connected with the electrode 50, and a seal part 35 composed of thermosetting resin and provided on the surface of the conductive part 30 so as to seal a gap with the upper case 22. The seal part 35 has a base 36 located on the surface of the conductive part 30, a first lip 37 projecting from the base 36, and a second lip 38 projecting from the base 36 at a position spaced apart from the first lip 37 to the outside of the gas passage and having a tip abutting against the upper case 22.SELECTED DRAWING: Figure 4 |
