A valve timing control apparatus for an internal combustion engine, including a drive rotation member, a follower rotation member, an electric motor, and a speed reducer including an internal gear portion, an eccentric cam on an inner peripheral side of the internal gear portion, rollers disposed between the internal gear portion and the eccentric cam, and a cage rotatable relative to the internal gear portion by rotation of the eccentric cam. A motor output shaft is arranged in series relative to the eccentric cam in an axial direction thereof. A needle bearing is rollably disposed on a part of an outer peripheral surface of the follower rotation member. The eccentric cam and the motor output shaft are press-fitted onto an outer peripheral portion of the needle bearing. The needle bearing extends over both the eccentric cam and the motor output shaft.
