The wire barrel (21) has a base plate (23) continuously extending from a ground terminal (11) in a longitudinal direction. Two core crimping pieces (25) extend from the opposite sides of the base plate (23). A thinned portion (27) is formed at least at a leading end of each core crimping piece (25) and is thinner than the base plate (23).
