The present invention provides a novel polyvinyl alcohol-based resin which is excellent in dispersion effect as a dispersion stabilizer and thickening effect as a thickener and has little influence on viscosity due to the presence of an inorganic metal salt or an organic metal salt. In a polyvinyl alcohol resin, a part of hydrogen atoms of a hydroxyl group is substituted with an alkyl group and / or an alkenyl group, and a carboxylate, a sulfonate, a sulfate, a phosphate, A polyvinyl alcohol-based resin, wherein one or more ionic groups selected from the group consisting of an amine salt and a quaternary ammonium salt are introduced into a side chain in the molecule.
