Provided is a tape cartridge which enables reliable feeding of the leading end of a printing tape, which has been pulled back inside a cartridge case, towards the outside from a tape delivery port.
The tape cartridge includes a cartridge case (45), a platen roller (44) that feeds an ink ribbon (R) and a printing tape (T), which are pressed between a printing head (31) and the platen roller, a tape delivery port (47) that is provided in the cartridge case (45), and that feeds the printing tape (T), after being separated from the ink ribbon (R), to outside of the cartridge case (45), and a delivery guide (52) having a front side guide section (53) and a rear side guide section (54) that extend from an edge of the tape delivery port (47) to the inside of the cartridge case (45) while spreading apart from each other. The front side guide section (53) of the delivery guide (52) has a guide surface (61) in which a leading-end section (53b) is at a greater distance from a virtual line (A) that passes through the tape pressing position and the center of the tape delivery port (47) than a base end section (53a).
