Wiring module

A wiring module to be coupled to a battery stack member including power storage elements that have electrode terminals and are stacked, the wiring module comprising:

• an electric wire;
• and
• a protector including an electric wire housing portion that has a groove shape extending in a first direction and in which the electric wire is arranged, wherein
• the electric wire housing portion includes
• a bottom wall,
• a pair of side walls that extend upward from two side edges of the bottom wall and that are opposite each other in a second direction that is perpendicular to the first direction, and
• at least one stopper piece that extends from one of the pair of side walls toward other one of the pair of side walls and with which the electric wire is less likely to be out of the electric wire housing portion,
• the stopper piece includes a basal end portion that is connected to the one of the pair of side walls and a distal end portion that is close to the other one of the pair of side walls, and
• a dimension of the basal end portion with respect to the first direction is greater than a dimension of the electric wire housing portion with respect to the second direction.
