A tape cartridge includes grasping portions that allow the tape cartridge to be grasped when the tape cartridge is installed to or detached from a tape printing apparatus and are disposed at two opposite places on a side surface of the tape cartridge, a platen that has a first reception portion in which the first shaft is inserted when the tape cartridge is installed and a second reception portion into which the second shaft is inserted when the tape cartridge is installed in the cartridge installation portion. The second reception portion is positioned on an opposite side over an imaginary line connecting the grasping portions with respect to the first reception portion and disposed at a position to which one of the two grasping portions farther from the first reception portion is closer than the other of the grasping portions.
