The wiring unit (20) is mounted on a battery stack (11L), and the battery stack (11L) is formed by laminating a plurality of laminated batteries (11) provided with electrode leads (12, 12A, 12B), and is provided with a joining portion (13) for joining the electrode leads (12, 12A) of the laminated batteries (11) in a mutually overlapping manner. The wiring unit (20) is provided with: a terminal (30); an electric wire (45), which is connected to the terminal (30); and a protector (50) for holding the terminal (30) and the electric wire (45). The terminal (30) is provided with: a main body portion (31); a connecting portion (32), which is configured to extend from the main body portion (31) and is oppositely connected, in a first direction, to the electrode leads (12, 12A) that constitute the joining portion (13); and at least one bent plate portion (33), which extends from the main body portion (31) to the laminated batteries (11) side in the first direction. The protector (50) is provided with: a protector main body (51); and at least one recess (52A), which is recessed towards the laminated batteries (11) side in the first direction relative to the protector main body (51) and accommodates the bent plate portion (33), wherein the bent plate portion (33) is inserted into the recess (52A), and thus is capable of moving in the first direction, such that the connecting portion (32) can come into contact with the electrode leads (12, 12A).
