A monomer having a plurality of tertiary alcoholic hydroxyl groups is provided. A useful polymer is obtained by polymerizing the monomer. From a resist composition comprising the polymer, a negative pattern which is insoluble in alkaline developer and has high etch resistance is formed at a high resolution.
