A connector includes a cylindrical-shaped housing inserting therein a wire, a shield shell disposed on an outer side of the housing, and a mounting member assembled with the housing and the shield shell. The mounting member includes a tubular portion inserted into a gap between the housing and the shield shell in a diameter direction of the housing and contacted with an end face of the housing. The shield shell includes a fixing portion fixed to the housing and a movable portion rotatably connected to the fixing portion. A fixing mechanism is provided between the movable portion and the tubular portion, moves the end face toward the tubular portion when the movable portion is rotated, and fixes the housing and the shield shell to the mounting member when the tubular portion and the end face closely contacted with each other.
