1. A battery module, comprising:
a plurality of cylindrical battery cells each having a positive electrode terminal and a negative electrode terminal on one side of each respective battery cell;
a busbar including an electrically conductive material and having a plate shape;
at least two types of connecting members each including an electrically conductive material, and having an elongated body, wherein one end in a direction in which the elongated body extends is joined to the busbar, and the other end is joined to one of the positive electrode terminal and the negative electrode terminal, the at least two types of connecting members having different joined areas depending on a joined terminal among the positive electrode terminal and the negative electrode terminal; and
a module case having an internal space in which the plurality of cylindrical battery cells is received,
wherein:
the plurality of cylindrical battery cells includes a particular cylindrical battery cell;
the module case has a first exposure hole and a second exposure hole;
at least part of the negative electrode terminal of the particular cylindrical battery cell is exposed to an outside of the battery module through the first exposure hole; and
at least part of the positive electrode terminal of the particular cylindrical battery cell is exposed to the outside of the battery module through the second exposure hole different from the first exposure hole.
