An object of the present invention is to provide a separation material in which the amount of non-specific adsorption is suppressed. SOLUTION: A porous polymer particle, a coating layer containing a polymer having a hydroxyl group, covering at least a part of the surface of the porous polymer particle, and formed between the porous polymer particle and the coating layer A crosslinked polymer comprising 90% by mass or more of a monomer unit comprising a film containing at least one of catechol and a catechol derivative, wherein the porous polymer particles are derived from a monomer having two or more double bonds, A separation material in which a polymer having a hydroxyl group has a sugar chain.
