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 the positive electrode terminal of one of two unit cells to be electrically connected among the plurality of unit cells and the negative electrode terminal of the other unit cell; 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. The first bus bar and the second bus bar are electrically connected to a voltage detection terminal for detecting a unit cell voltage. 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 the 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 via the first metal member.
