PROBLEM TO BE SOLVED: To provide a vinyl alcohol polymer useful for producing an inkjet recording material having an ink receiving layer having no cracks on the surface, high glossiness, excellent ink absorption and high transparency. To do. SOLUTION: A monomer unit having a specific polyoxyalkylene group, the viscosity average polymerization degree P, and the content S of the monomer unit having a polyoxyalkylene group with respect to all the monomer units in the polymer. A vinyl alcohol polymer in which the product P × S with (mol%) and the number n of oxyalkylene repeating units in the monomer unit having a polyoxyalkylene group satisfy a specific relational expression.
