A recording tape cartridge has a case which is substantially rectangular, and which rotatably accommodates a single reel on which a recording tape is wound; an opening formed at a corner portion of the case at a side of loading the case into a drive device, the opening being for pulling-out of a leader member attached to an end portion of the recording tape; and a shielding member sliding so as to open and close the opening. A dustproofing wall, which overlaps with a distal end of the shielding member when the shielding member closes the opening, is formed at a peripheral edge of the opening.
