A leader pin is attached to an end portion of recording tape housed in a recording tape cartridge, and an opening for allowing the leader pin to be pulled out is formed in a side wall of a case. Holding portions that hold the leader pin are formed in the vicinity of the opening in the case. The leader pin includes, on both ends of a body portion, large diameter portions and flange portions disposed via neck portions on the large diameter portions. The holding portions include slit portions that open towards the opening and into which the neck portions enter, first concave portions that house the large diameter portions, and second concave portions that house the flange portions. The outer diameter of the flange portions of the leader pin is formed so as to be smaller than the outer diameter of the large diameter portions.
