The present invention aims to provide an adsorption separation material which can selectively adsorb rare earth elements, is simple in apparatus and operation, and is excellent in adsorption and recovery ability. The adsorption separation material of the present invention is an adsorption separation material for selectively recovering a rare earth element dissolved in an aqueous solution, in which at least one diglycolamic-acid-type ligand represented by the following general formula (2) is bonded to a polymer base material by graft polymerization. (in the formula (2), R represents a hydrogen atom, an alkyl group having a carbon number of from 1 to 3, an alkylene group having a carbon number of from 1 to 3, an acyl group having a carbon number of from 1 to 2, or an aldehyde group, and * represents a bond.)
