Abstract: A liquid supplier can be attached to and detached from a case of a liquid ejection device, and includes a connection member located at an end of the case. The connection member includes a liquid outlet member including a liquid outlet port and a connection port, a container-side electric connector, a first receiving portion that receives a first positioning portion of the liquid ejection device, and a second receiving portion that receives a second positioning portion of the liquid ejection device. The width of the liquid supplier in the Z direction is smaller than a width in the Y direction and a width in the X direction. The liquid supplier further includes a tube whose one end is connected to the connection port, and into which liquid is injected from another end that is located outside the liquid ejection device.

Abstract: The liquid container has a spacer member provided in the liquid storage portion. When three directions orthogonal to each other are assumed to be a D direction, a T direction, and a W direction, in the D direction, a direction from a liquid outlet portion toward the other edge portion of the bag is assumed to be a +D direction, and the opposite direction to the +D direction is assumed to be a −D direction, and a direction in which the dimension of the outer shape of the liquid container is smallest is assumed to be the T direction, and the spacer member has, on the +D direction side, a face inclined such that the dimension in the T direction of the spacer member increases from the +D direction side toward the −D direction side.
