Claim Text:
1. A monolithic organic porous body comprising: a monolithic organic porous intermediate body which comprises a skeleton comprising a first polymer material, and which has a continuous macropore structure comprising cellular macropores that overlap to form openings having an average diameter of 20 to 200 μm, and a second polymer material which adheres to portions of a surface of the skeleton throughout the monolithic organic porous intermediate body, so as to thicken the skeleton throughout the monolithic organic porous intermediate body, wherein the monolithic organic porous body has a thickness of 1 mm or more and a total pore volume of 0.5 to 5 ml/g, and wherein in an SEM image of a cross-section of the continuous macropore structure in a dry state, a cross-sectional area of a skeleton is 25 to 50% of a total area of the SEM image, the monolithic organic porous body being produced by performing: a first step comprising stirring a mixture of an oil-soluble monomer that does not include an ion-exchange group, a surfactant, and water to prepare a water-in-oil emulsion, and polymerizing the water-in-oil emulsion, so as to obtain the monolithic organic porous intermediate body that has a total pore volume of 5 to 16 ml/g, a second step comprising mixing a vinyl monomer, a crosslinking agent that includes at least two vinyl groups in one molecule, an organic solvent that dissolves the vinyl monomer and the crosslinking agent, but does not dissolve a polymer produced by polymerizing the vinyl monomer, and an initiator, and a third step comprising polymerizing the mixture obtained by the second step in a stationary state in a presence of the monolithic organic porous intermediate body, so as to obtain the monolithic organic porous body having a skeleton thicker than the skeleton of the monolithic organic porous intermediate body.
