Female terminal fitting

Provided is a female terminal fitting capable of improving the durability of an elastic contact piece. A female terminal fitting (10) is provided with: a cylindrical main body section (20); and an elastic contact piece (40) which extends from the fulcrum portion (41) toward the free end portion (42) inside the main body portion (20) and which is in contact with the male tab (120) inserted into the opposite side of the main body portion (20). The free end (42) side of the elastic contact piece (40) is displaced in the plate thickness direction of the elastic contact piece (40). The main body part (20) has a first restricting part (31) and a second restricting part (32), and the first restricting part (31) and the second restricting part (32) make contact with the elastic contact piece (40) and restrict the displacement range of the free end part (42) side to be smaller than or equal to the plate thickness of the elastic contact piece (40). 提供一种能提高弹性接触片的耐久性的阴端子零件。阴端子零件(10)具备：筒状的主体部(20)；和弹性接触片(40)，在主体部(20)的内部从支点
