Abstract: A liquid supply unit is provided with a liquid supply part, an outer peripheral wall, contact portions and a positioning portion.

Abstract: A liquid supply unit includes a first wall part to a seventh wall part. The first wall part includes a liquid supply part and an outer peripheral wall surrounding the liquid supply part and protruding in a direction from the second wall part toward the first wall part so as to come into contact with a sealing member of a carriage. The liquid supply part has a filter for supplying liquid to a liquid introduction part upon coming into contact with the liquid introduction part. A distance between the third wall part and the fourth wall part is larger than a distance between the fifth wall part and the sixth wall part. In a plan view in a direction from the first wall part toward the second wall part, a length of the outer peripheral wall in a first direction from the third wall part toward the fourth wall part is larger than a length in a second direction from the fifth wall part toward the sixth wall part.

Abstract: A liquid container unit includes a liquid container and a container holder. The liquid container has an injection port for a liquid, a liquid containing portion capable of containing the liquid that is injected from the injection port, and a supply port capable of connecting to a liquid supply member in communication to a liquid ejection head of a liquid ejecting apparatus. The container holder is capable of holding the liquid container. The container holder holds the liquid container in a state where a first portion of the liquid container including at least the injection port is displaceable in a relative manner with respect to the container holder.
