Abstract
An object of the present invention is to provide a gel material including a solvophilic polymer having a μm-scale porous structure. A polymer gel in which solvophilic polymer units are cross-linked with each other, wherein the polymer gel contains a solvent and has a three-dimensional network structure having two regions: a first region in which the polymer units are densely present and a second region in which the polymer units are sparsely present, and a mesh size composed of the first region is from 1 to 500 μm.
