A secondary battery module (100) includes an annular member (40) making a tip end (21a) of a connection terminal (21) of a bus bar (20) and a tip end (31a) of a voltage detection terminal (31) inserted therein in an axial (A) direction to be aligned with each other in terms of directions. The annular member includes an elastic deformation portion (41) biasing the connection terminal and the voltage detection terminal in directions of making the connection terminal and the voltage detection terminal press each other. Accordingly, reliability to deal with an external cause is high, and an assembling operation is facilitated. |
