To provide: a monomer having a polyalkylene glycol chain preferably used in various industrial applications such as detergent builder compositions for clothes and bodies, water-treatment agents, and pigment dispersants; and a polyalkylene glycol polymer using such a monomer as a raw material. A polyalkylene glycol monomer having a polymerizable double bond and a polyalkylene glycol chain, wherein the polyalkylene glycol monomer has a hydrophobic part in the polyalkylene glycol chain and/or at a terminal of the chain, and the polymerizable double bond is derived from allyl glycidyl ether, and a polyalkylene glycol monomer having a monomer unit derived from the above-mentioned polyalkylene glycol monomer, wherein the polyalkylene glycol polymer is a polyalkylene glycol polymer having a carboxylic acid group and/or a sulfonic acid group.
