ABSTRACT:
A recording medium cartridge which is capable of preventing a drop in aesthetic quality by preventing damage to a printed layer for writing during ultrasonic welding is presented. As a printed layer (20), a writing-enabling filler (21), and resin particles (22) having an average particle diameter equal to or greater than the average particle diameter of the writing-enabling filler (21) mentioned above are included in an ink (23). The resin particles (22) come into contact with a welding horn (9), and prevent the writing-enabling filler (21) from falling out or changing shape due to ultrasonic vibration.
