A female terminal fitting (10) has a tubular main body (11) with front and rear ends and a bottom wall (13). A fold (20) is folded back from the front end of the bottom wall (13) and a resilient contact piece (18) extends back from the fold (20) to face the bottom wall (13). A bulge (23) on the resilient contact piece (18) includes a contact (25) for contacting a tab (T) of a male terminal fitting (M). The contact (25) is pressed by the tab (T) so that the resilient contact piece (18) is deformed with the fold (20) as a supporting point and an extending end (26) thereof contacts the bottom wall (13). The resilient contact piece (18) has a front narrowed portion (29) between the fold (20) and the contact (25) and a rear narrowed portion 30 between the contact (25) and the extending end (26).
