Provided are a novel polymer having a sulfonic group, a sulfonic acid ester group, or a derivative thereof incorporated therein, a method of producing the polymer, and a novel compound suitable for producing the polymer. A polymer is characterized by containing a unit represented by the following formula (1): wherein R1w and R1x are each independently a halogen atom or a hydrogen atom, R1y is a CH3 group or a hydrogen atom, and any one of R1a, R1b, and R1c is a sulfonate group represented by SO3R1f. |
