In a ribbon cassette of the invention, a driving mechanism that circulates an endless ink ribbon to move to and from a print portion is accommodated in a main body portion of a case. The case has a pair of arm portions serving as an inbound path and an outbound path of a circular movement. The interior of the main body portion of the case is divided by a virtual straight line linking an inlet portion of the ink ribbon from the arm portion serving as the outbound path and an outer circumferential surface of the driving roller over which the ink ribbon is stretched, and a roller-shaped ink tank impregnated with ink is provided on one of the divided sides. The ink tank is disposed in a positional relation that an outer peripheral surface of a cylindrical column is in close proximity to the virtual straight line, and an outer circumferential surface of a transfer roller is brought into contact with an outer circumferential surface on a side closer to the virtual straight line. A portion of the ink ribbon to the driving roller is stretched over an outer circumferential surface of the transfer roller on an opposite side to a contact portion with the ink tank.
