A female terminal fitting (10) is provided with a box-shaped main portion (11) into which a mating tab (61) is insertable, and a resilient touching piece (12) having a projection as a contact projection (32) that can contact the tab (61) is provided in the main portion (11). The tab is formed by folding the opposite widthwise sides of a metal plate in a thickness direction and causing the end edges of the folded parts to face each other. A flat surface (35) of the contact projection (32) comes into flat contact with the tab (61) while crossing over the facing ends (64) when the tab (61) is inserted properly into the main portion (11). Accordingly, edges (67) of the facing ends (64) do not sharply act on the contact projection (32).
