The present invention provides a polymer which has at least one or more of a repeating unit represented by a following general formula (1
a
), a repeating unit represented by a following general formula (2
a
) and a repeating unit represented by a following general formula (3
b
), and a repeating unit represented by a following general formula (1
c
), and a positive resist composition which contains as a base resin the polymer. Thereby, there can be provided a positive-resist composition having high sensitivity and high resolution in exposure with a high energy beam, wherein line edge roughness is small since swelling at the time of development is suppressed, and the residue after development is few.
