The present invention aims to provide a novel vinyl monomer having a diglycolamic-acid-type ligand, which is useful for producing an adsorption separation material for separating and recovering rare earth elements. The vinyl monomer of the present invention has a diglycolamic-acid-type ligand represented by the following general formula (1): (in the formula (1), R 1 represents a hydrogen atom or an alkyl group having a carbon number of from 1 to 3, when R 1 is a hydrogen atom, X represents a single bond or a divalent organic group having a carbon number of from 2 to 7, which may have a substituent, and when R 1 is an alkyl group having a carbon number of from 1 to 3, X represents a single bond or a divalent organic group having a carbon number of from 1 to 7, which may have a substituent. n represents 0 or 1, when n is 0, R 2 represents a hydrogen atom, an alkyl 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 when n is 1, R 2 represents an alkylene group having a carbon number of from 1 to 3.)
