Therefore, in the conductive module 1, since the cover 60 can receive the reaction force generated in the bent portion 10B of the aggregated electric wire 10X, it is possible to suppress the reaction force from acting on other portions. Therefore, in the conductive module 1, it is possible to suppress the displacement of the aggregated electric wire 10X from the wiring route. Further, in this conductive module 1, it is possible to suppress deformation of peripheral components due to the reaction force of the bent portion 10B of the aggregated electric wire 10X and improve the durability.

You can

In addition, in the conductive module 1, the aggregate electric wire 10X requires an extra length when the connector 16 and the mating connector Ub1 are inserted and removed. Therefore, in the cover 60 and the holding mechanism 70, the space between the cover main body 61 and the connection target housing 1c can accommodate the extra length of the aggregated electric wire 10X before the fitting and connection, and the connector 16 can be installed.
