PROBLEM TO BE SOLVED: To provide an affinity adsorbor suitable for the adsorptive refining operation such as the adsorptive recovery of valuables such as protein or the like, adsorptive removal or the like of impurities, etc. and enabling adsorptive refining at a high speed, and its manufacturing method. SOLUTION: Affinity beads are constituted so that a functional group having a protein adsorption capacity is fixed to the surfaces of polymeric base material particles through a polymeric side chain and are characterized in that the average particle size of the polymeric base material particles is 10-80μm, the density of the polymeric side chain is 1.5-30 g/m<SP>2</SP>per the surface area of the polymeric base material particles and the fixing concentration of the functional group having the functional group having the protein adsorption capacity is 1 mmol/g or above per the weight of the affinity beads. After glycidyl methacrylate is bonded to polyethylene base material particles with the average particle size of 10-80μm in a graft ratio of 35-500% by a radiation graft polymerization method, the functional group having the protein adsorption capacity is introduced into and fixed to the epoxy ring in the glycidyl group by chemical reaction.
