A tape cassette comprises an impedance roller which is set on the opposite side of a magnetic tape to a magnetic head closely upstream thereof as viewed from the direction in which the magnetic tape runs. The impedance roller presses the magnetic tape toward the magnetic head, thereby preventing the magnetic tape from being shaken.
