A connector may have a housing having a housing part housing a flat cable, and a mounting member mounted to the housing for locking the flat cable. The mounting member may have a mounting part mounted to at least one of the housing and a circuit board, an elastic part extending in a width direction of the flat cable, an extending part extending in the width direction of the flat cable, and an engaging part engaging with an engaged part formed on the flat cable. The mounting part may be connected to an end part in the width direction of the elastic part. An intermediate region of the extending part may be connected to an intermediate region in the width direction of the elastic part. The engaging part may be connected to an end part in the width direction of the extending part. The elastic part may be elastically deformable in a thickness direction of the flat cable.
