a liquid container configured to store a liquid;
a lid part configured to cover the liquid container;
a liquid holding member stored in the liquid container and configured to hold the liquid; and
a projection member connected to the liquid holding member,
wherein the liquid holding member has a first surface facing the lid part,
wherein the lid part includes an atmosphere communication path that communicates inside and outside of the liquid container,
wherein the atmosphere communication path includes an opening that is open to the inside of the liquid container,
