To provide a connector that increases the amount of elastic deformation of a beam and can improve the contact stability between a flat electrical wire and a terminal while restraining an increase in the difference between the position of a cam in the anteroposterior direction and the position of a pressing portion formed on the cam, a pressing portion that pushes flat electrical wire is formed on the lower surface of center beam of rear connecting terminal. Cam of actuator is positioned between upper beam and center beam of rear connecting terminal. Inclined surface that extends at an angle upward and backward is formed on the upper surface of center beam. Cam pushes inclined surface down.
