A holding wall (6) of a connector housing (1) has terminal holding holes (7) for receiving terminal fittings. Two tight holding walls (11) are formed at opposite sides of each terminal holding hole (7) on the outer surface of the holding wall (6). The terminal fitting is pressed into the terminal holding hole (7) and between the tight holding walls (11). Further, the terminal holding holes (7) are formed by molding pins (14) having a length substantially equal to the thickness of the holding wall (6) and contact plates (13) that contact the leading ends of the molding pins (14). Thus, the molding pins (14) can be short and are less likely to deform when subjected to pressure from resin during molding.
