1. A battery module comprising:
a plurality of battery cells; and
busbars connected to external terminals of the battery cells,
the busbars include a busbar having a pair of terminal portions, a current-carrying portion connecting the pair of terminal portions, and a fuse provided in the current-carrying portion,
the current-carrying portion surrounding the fuse such that a part of the current-carrying portion is disposed between the fuse and the battery cells,
the pair of terminal portions are provided at one end and the other end of the busbar in a first direction,
the current-carrying portion, in a state of unfolded to a flat surface, in a second direction orthogonal to the first direction, has one end connected to the pair of terminal portions and the other end provided with the fuse, and
the fuse is located inside the current-carrying portion bent in a tubular shape extending in the first direction.
