ABSTRACT OF THE DISCLOSURE: A process for preparing an acrylic or methacrylic acid ester comprising esterifying the acrylic or methacrylic acid with an alcohol in a water-insoluble and non- reactive organic solvent in the presence of an acid catalyst, the volume ratio of the organic solvent phase to an aqueous solution phase of the acid catalyst being as small as 0.1 to 1.0, whereby an reactor is allowed to be small-sized and a conversion of the esterification is kept high. The acrylic or methacrylic acid ester is useful as a starting material of an acrylic resin or acrylic resin coating, an adhesive or the like.
