The present invention provides a recording tape cartridge with a retention structure capable of stabilizing and retaining a memory board without deformation of the memory board. A recording tape cartridge includes a case for accommodating a reel on which recording tape is wound, the case formed by an upper case and a lower case and a non-contact memory board, on which various information is stored and which is disposed at a specific angle within the case. The lower case is formed with a position control member of substantially a C-shape in plan view for controlling the position of the memory board, and a support member for supporting the bottom face of the memory board at substantially the central portion thereof. The upper case is formed with retaining members that face portions of the top face of the memory board at both ends in the memory board length direction.
