The purpose of the present invention is to provide an adsorption separation material enabling selective adsorption of a rare earth element, and exhibiting excellent adsorption and recovery performance using a simplified device and operation. This adsorption separation material selectively recovers a rare earth element dissolved in an aqueous solution, wherein at least one diglycol amide acid-type ligand represented by the following general formula (2) is bonded to a polymer substrate by graft polymerization. (In formula (2) : R represents a hydrogen atom, a C1-3 alkyl group, a C1-3 alkylene group, a C1-2 acyl group, or an aldehyde group; and * represents a bond).
