Abstract
The present invention provides a separation material including porous polymer particles that comprise at least one of styrene and divinylbenzene as a monomer unit at a proportion of 90% by mass or more based on the total amount of the monomers; and a coating layer that comprises a macromolecule having hydroxyl groups and covers at least a portion of the surface of the porous polymer particles, wherein the coating amount provided by the coating layer is 1 to 15 mg/mper unit specific surface area of the porous polymer particles.
