Abstract

A liquid absorber includes a plurality of small parts each including a first layer containing fibers, a second layer containing fibers, and a third layer which contains a water absorbing resin and which is provided between the first layer and the second layer. When the water absorbing resin is measured in accordance with a plastic thermogravimetric measurement method defined by JIS K 7120: 1987 under measurement conditions in which a sample amount is 5 to 15 mg, a temperature increase rate is 10.0°C/min, and a measurement atmosphere is nitrogen, from a TG curve obtained thereby, the ratio of a weight decrease amount of the water absorbing resin at 400°C with respect to an initial weight thereof is 0.050 to less than 0.500.
