Claim 6:
7. A liquid container comprising:
a case having a liquid introduction port through which liquid is introduced and a storage portion that stores the liquid; and
an absorber stored in the case and configured to absorb the liquid, wherein
the absorber includes
a first ring-shaped resin group in which a plurality of absorbent resins that swell by absorbing the liquid are arranged in a ring shape,
a second ring-shaped resin group in which a plurality of absorbent resins that swell by absorbing the liquid are arranged in a ring shape with a space between the second ring-shaped resin group and the first ring-shaped resin group, and
a substrate that supports the first ring-shaped resin group and the second ring-shaped resin group and that allows the liquid to permeate therethrough, and
when the absorbent resins swelling by absorbing the liquid, at least some of the absorbent resins of the first ring-shaped resin group are spaced apart from the absorbent resins of the second ring-shaped resin group, wherein
the absorber includes
a first substrate that supports the first ring-shaped resin group and the second ring-shaped resin group and
a second substrate that supports the first ring-shaped resin group and the second ring-shaped resin group,
the first substrate and the second substrate are stacked on top of each other in a stacking direction in the case, and
in plan view in the stacking direction, the first ring-shaped resin group and the second ring-shaped resin group supported in the first substrate and the first ring-shaped resin group and the second ring-shaped resin group supported in the second substrate are positioned such that at least portions of the first and second ring-shaped resin groups supported in the first substrate do not overlap at least portions of the first and second ring-shaped resin groups supported in the second substrate.
