In the connector, each terminal has a base portion, a rear upper beam, a front upper beam, a rear lower beam, and a front lower beam. The actuator includes a cam portion pushing the rear upper beam upwards, and the rear lower beam includes a fixed portion. The front lower beam includes a contact point which establishes contact with the flat cable, and a front end of the lower surface of the front lower beam establishing contact with the upper surface of the bottom portion of the housing. The contact point is positioned to the rear of the upper end of the lower surface of the front lower beam, and the front lower beam and the rear lower beam curve upward when the rear upper beam is pushed upwards, the front end of the lower surface of the front lower beam and the fixed portion serving as the support point.
