Provided are graft copolymer particles enabling introduction of adsorptive functional groups adsorbing metals and others, a method for producing same, and an adsorbent using same. (1) Porous graft copolymer particles containing graft chains introduced into porous particles (particle surface having an average pore diameter of 0.01-50 &#x3bc;m) including at least one resin selected from olefin resins, water-insoluble modified polyvinyl alcohol resins, amide resins, cellulosic resins, chitosan resins and (meth)acrylate resins. (2) A method for producing porous graft copolymer particles including (I) melt-kneading a polymer A and a polymer B other than the polymer A to obtain a compound material, (II) extracting and removing the polymer B from the compound material to obtain a porous material of the polymer A, (III) granulating the porous material, and (IV) introducing graft chains into the porous particles. (3) An adsorbent of porous graft copolymer particles.
