[Problem] The present invention addresses the problem of providing a gel material comprising a solvophilic polymer having a micrometer-scale porous structure. [Solution] A polymer gel in which solvophilic polymer units are cross-linked to each other, wherein the polymer gel contains a solvent, and has a three-dimensional net-like structure having two regions, i.e., a first region in which the polymer units are present densely and a second region in which the polymer units are present sparsely, and the sizes of nets formed in the first region fall within the range from 1 to 500 μm. |
