A male connector to be connected to a female connector provided at a housing accommodating a vehicle-mounted electrical device includes a contact point to be connected to a contact of the female connector, a cable connected to the contact point, and a shield shell covering the contact point. A fixing structure for the male connector includes a bolt for fixing the shield shell to the housing, on the contact point side, and a clamp for fixing the cable to the housing, on the cable side. The fixed state of the cable established by the clamp is such a state as to allow for more movement of an object to be fixed than does the fixed state of the shield shell established by the bolt.
