The present invention provides a separation material that is excellent in liquid permeability when used as a column, reduces the amount of non-specific adsorption of biopolymers, and has a high protein adsorption amount, and a column equipped with the separation material. SOLUTION: A porous polymer particle containing a polymer containing a styrene monomer as a monomer unit, a first graft chain which is a zwitterionic polymer bonded to the surface of the porous polymer particle, and the first And a second graft chain, which is a polymer having a hydroxyl group, bonded to the graft chain.
