Technology enabling stably attaching a cartridge having a fluid supply port and a waste fluid inlet to a fluid ejection device. The cartridge has a bottom wall with a fluid supply port for supplying fluid to the fluid ejection device, and a waste fluid inlet for recovering waste fluid from the fluid ejection device, a first side wall having a first contact part capable of contacting a first fastening member of the cartridge holder when the cartridge is installed in the cartridge holder, and a second side wall having a second contact part capable of contacting a second fastening member of the cartridge holder when the cartridge is installed in the cartridge holder. When looking at the cartridge from the bottom wall side, an imaginary first line passing through the first contact part and the second contact part passes between the fluid supply port and the waste fluid inlet.
