A connector (10) includes terminals (14) and a housing (12) with terminal accommodating portions (36) to accommodate the terminals (14). Each terminal (14) includes a terminal connecting portion (18) extending in a front-rear direction and a vertical wire connecting portion (20) perpendicular to the front-rear direction. A first coupling portion (22A) extends in the front-rear direction from a rear end of the terminal connecting portion (18), and a second coupling portion (22B) extends vertically from an extending end of the first coupling (22A) to the wire connecting portion (20). Projections (30) project from sides of the first coupling portion (22A) in a third direction perpendicular to the front-rear direction and the vertical direction. Grooves (42) are open in inner walls (38A) of the terminal accommodating portion (36) facing each other in the third direction, and the projections (30) contact inner walls of the grooves (42) in the vertical direction.
