PROBLEM TO BE SOLVED: To provide an ink ribbon cassette which can improve a printing quality by reducing a frictional resistance applied to axial parts of a feeding core and a winding core when the feeding core and the winding core are rotated and driven, and by making delivering and winding of an ink ribbon smooth. SOLUTION: Projections 20a and 20b are respectively formed in bearings of at least one case among bearings 6b and 7b of a first case 5 and bearings 14b and 15b of a second case 13 in which respective axial parts 3d and 4d of the feeding core 3 and the winding core 3 are pivoted.
