A small-capacity liquid container capable of preventing a trouble due to a pressurized deformation of a large-capacity liquid container even when plural liquid containers having different capacity are densely arranged. A liquid container is an improvement of a small-capacity liquid container of a plurality of liquid containers selected from a container lineup at least including a large-capacity liquid container and a small-capacity liquid container having an entire length smaller than that of the large-capacity liquid container, the plurality of liquid containers each having a substantially rectangular parallelepiped shape, being mounted on a container holder of a liquid consuming apparatus in a state where pairs of largest faces thereof are adjacent to each other, and supplying a liquid with an introduction of a pressurizing fluid from the liquid consuming apparatus. The small-sized liquid container includes a liquid containing section containing the liquid, a container body accommodating the liquid containing section in a pressurizing space into which the pressurizing fluid is introduced, and an extension section formed by allowing the container body to extend toward the rear end in a mounting direction in which the liquid container is mounted on the container holder.
