A rotary connector device includes a stator, a rotator rotatable relative to the stator, a base ring arranged between the stator and the rotator, a flexible flat cable (14), and a rotating roller. The flexible flat cable (14) has a conductor part (14a), and is configured to electrically connect the stator side and the rotator side to each other. The rotating roller is rotatably supported on the base ring, and brings an outer circumferential surface thereof into contact with the flexible flat cable (14), thereby guiding it. The rotating roller is molded by using a die. When a plane including a parting line that is formed at the outer circumferential surface of the rotating roller at a time of the molding is defined as an imaginary plane (90), the imaginary plane (90) is perpendicular to an axis of the rotating roller and does not overlap the conductor part (14a) of the flexible flat cable (14).
