摘要

PROBLEM TO BE SOLVED: To provide a bus bar module capable of preventing a foreign material from above from adhering to a circuit component without providing an upper cover covering the upper side of the circuit component. ! SOLUTION: A bus bar module 14 comprises a plurality of bus bars 26 to which a plurality of battery cells 16 of a battery assembly 12 are connected in series, a battery monitoring IC 28 related to the plurality of battery cells 16, and a holding member 30 which holds the bus bar 26. The battery monitoring IC 28 is arranged on the lower side of the holding member 30 so that the upper surface side of the battery monitoring IC 28 is covered by a holding plate part 44 of the holding member 30. The battery monitoring IC 28 comprises a gas exhaust duct 58 including a gas exhaust passage 63 for exhausting the gas produced in each battery cell 16. The gas exhaust duct 58 is provided in the holding member 30 so as to cover the lower surface side of the battery monitoring IC 28. The holding member
