Conductive module and battery pack

A battery pack comprising:

• a plurality of arranged battery cells;
• and
• a plurality of conductive modules that electrically connects the battery cell and an arithmetic processing device of a battery monitoring unit monitoring a battery state of the battery cell, wherein
• the conductive module includes:
• a first conductive member that is electrically connected to one of two electrode terminals included in a battery cell being a connection target, the connection target being at least one of a plurality of arranged battery cells;
• a second conductive member that is a conductive member extending in an arrangement direction of the plurality of battery cells and electrically connects the arithmetic processing device to the first conductive member;
• a circuit protection member that includes a first electrical connection portion electrically connected to an electrical connection portion of the first conductive member, a second electrical connection portion electrically connected to an electrical connection portion of the second conductive member, and a fuse element arranged between the first electrical connection portion and the second electrical connection portion;
• a first electrical connection structural body that electrically connects the electrical connection portion of the first conductive member and the first electrical connection portion between the first conductive member and the circuit protection member;
• a second electrical connection structural body that electrically connects the electrical connection portion of the second conductive member and the second electrical connection portion between the second conductive member and the circuit protection member;
• and
• a housing member that houses the circuit protection member and the first and second electrical connection structural bodies,
• the second electrical connection structural body includes a linking portion, which is a part that extends in an intersecting direction with respect to the arrangement direction of the plurality of battery cells and physically and electrically connects the electrical connection portion of the second conductive member, and enables the respective second conductive members of all the conductive modules arranged along the arrangement direction with respect to an aggregate formed of the plurality of battery cells to be arranged side by side along the intersecting direction,
• the linking portion is arranged at a position to cause the second conductive member of the conductive module to which the linking portion belongs to linearly extend along the arrangement direction of the plurality of battery cells,
• the linking portion is arranged at a position protruding from the housing member in a direction orthogonal to a reference plane as viewed in the arrangement direction and extends along the reference plane, the reference plane being a plane along the arrangement direction of the plurality of battery cells and along a wall surface of the aggregate formed of the plurality of battery cells, and
• the linking portion has a planar linking surface along the intersecting direction on a protruding direction side thereof with respect to the housing member, and physically and electrically connects the electrical connection portion of the second conductive member of the module provided with the linking portion to the linking surface with the electrical connection portion exposed to an outside.
