A combined terminal fitting assembly is provided to fix ends of three or more wires to one fixing place. Engaging portions (25, 26, 34, 35) for holding a right terminal fitting (TR) and a left terminal fitting (TL) assembled are provided on both upper and lower surfaces of terminal main bodies. Thus, the right terminal fittings (TR) and the left terminal fittings (TL) can be placed alternately one over another. As a result three or more wires (W) can be fixed to one fixing place. Upon assembling, the wire (W) of the right terminal fitting (TR) and the wire (W) of the left terminal fitting (TL) are brought gradually closer to each other from most distant positions. Thus, the left and right wires (W) neither overlap nor interfere with each other.
