Abstract
This secondary cell module has: a plurality of unit cells, each having a pair of positive and negative electrode terminals; a first bus bar providing an electrical connection between unit cells; and a second bus bar disposed on at least two unit cells of the plurality of unit cells and electrically connected to an external terminal. In addition, the present invention is characterized in that the second bus bar has a first metal member connected to the positive or negative electrode terminal, a second metal member connected to the external terminal, a third metal member connected to a voltage detection terminal, a first linkage member connecting the first metal member to the second metal member, and a second linkage member connecting the first metal member to the third metal member, and the first linkage member and the second linkage member are connected to each other via the first metal member.
