It is aimed to provide a connector capable of reducing the number of components. A connector (100) includes a plurality of terminal fittings (50) having wires (90) connected to rear end parts, and a dielectric (20) for accommodating the plurality of terminal fittings (50) with the wires (90) drawn out rearward. The dielectric (20) includes a holding member (30) having a plurality of terminal accommodation chambers (34) separated in two upper and lower stages and laterally arranged in parallel, upper and lower surfaces of the holding member (30) being formed with openings (35) enabling the terminal fittings (50) to be mounted into the terminal accommodation chambers (34), and a front member (40) integrally formed with a pair of upper and lower closing portions (41, 41) for individually closing the openings (35) on an upper surface side and the openings (35) on a lower surface side, the front member (40) being assembled with the holding member (30) from front.
