The present invention provides a polymerizable tertiary ester compound represented by the following general formula (1a) or (1b). There is provided a polymerizable ester compound useful as a monomer for a base resin of a resist composition having a high resolution and a reduced pattern edge roughness in photolithography using a high-energy beam such as an ArF excimer laser light as a light source, especially in immersion lithography, a polymer containing a polymer of the ester compound, a resist composition containing the polymer as a base resin, and a patterning process using the resist composition.
