A wiring module is directed to a wiring module configured to be attached to a plurality of power storage elements having electrode terminals. The wiring module includes: a plurality of busbar units: and wires connected to the busbar units. Each of the busbar units includes: a busbar connected to the electrode terminals; a circuit board; and a fixing means configured to fix the circuit board to the busbar. A conductive path is routed on the circuit board, and the conductive path includes: a connection land electrically connected to the busbar; and a wire land soldered to the corresponding wire. The busbar includes a crimping part that fixes the wire, and the wire is interposed between the crimping part and the circuit board.

Wiring module

An external connection bus bar to be connected to a storage element group having a plurality of storage elements and having an output electrode terminal for outputting electric power to an external circuit includes a main body portion to be connected to the output electrode terminal, an external connection terminal to be connected to an external circuit, and a circuit board connection portion to be soldered to a bus bar land provided on the circuit board. The external connection terminal is provided between the main body portion and the circuit board connection portion.
