A male terminal (10) includes a tab (11) extending in a front-rear direction. A female terminal (60) includes a base (64) in the form of a flat plate extending in the front-rear direction, a contact piece (67) rising from one side of the base (64) and further curved so that a tip faces the base (64), and an opening (69) opens between the tip of the contact piece (67) and the base (64) on a side facing a rising part of the contact piece (67). The tab (11) includes a part configured to be sandwiched resiliently between the base (64) and the contact piece (67) and contacts a leading end edge of the contact piece (67) along the front-rear direction when the male and female terminals (10, 60) are connected and a part projecting laterally outwardly through the opening (69).
