Abstract: A cartridge includes a liquid container and an adaptor. The liquid container has a liquid storage containing a liquid to be supplied to a printing apparatus, a liquid supply section configured to supply the liquid contained in the liquid storage to a liquid introduction section, and an adaptor mounting section. The adaptor is mounted on the adaptor mounting section and has a terminal placement section in which a cartridge-side terminal electrically connected to an apparatus-side terminal is disposed and an insertion aperture through which the liquid introduction section passes. The adaptor mounting section is provided with a mounting mechanism for mounting the adaptor, which has a predetermined constant shape.

Abstract: A liquid container includes a liquid containing body that contains liquid, a case that houses the liquid containing body, and a display board portion on which identification information regarding the liquid container is gathered and displayed.
