A wiring module is for attachment to a power module in which power elements that store or generate electrical power are arranged side-by-side. The wiring module includes: an insulating protector that houses interconnection conductors for interconnecting the power elements; detection wires that are housed in the insulating protector, extend from a side corresponding to the power elements, and detect a state of the power elements; a connector that is provided at an end portion of the detection wires and is arranged inside the insulating protector; and a movement restricting means that is provided in the insulating protector and is for restricting movement of the connector by locking the connector.
