Abstract

To provide an absorber having high absorption efficiency.SOLUTION: A composite absorber (1) according to the present invention is for absorbing liquid, the composite absorber (1) comprising a polymer absorbent (4) having hydrophilic continuous skeletons and continuous pores. The polymer absorbent (4) has an initial amount of liquid absorption of 5 g / g or more after a lapse of 5 seconds since the application of 40 g / cm2 load, and has an amount of liquid absorption after a lapse of 20 seconds or longer that is 110% or more of the initial amount of liquid absorption.SELECTED DRAWING: Figure 4
