A shielded board connector (20) includes a terminal holding member for shielding (21) and left and right terminal fittings (31). An unshielded board connector (35) includes a terminal holding member for unshielding (36) and left and right terminal fittings (31). In the pair of terminal fittings (31) in the shielded board connector (20), an interval (Pw) of tab-like connecting portions (32) is wider than an interval (Po) of board connecting portions (34). In the pair of terminal fittings (31) of the unshielded board connector (35), an interval (Pn) of tab-like connecting portions (32) is narrower than an interval (Po) of board connecting portions (34). The interval (Po) of the board connecting portions for shielding (34) and the interval (Po) of the board connecting portions for unshielding (34) are substantially equal.
