PROBLEM TO BE SOLVED: To provide a monomer including a lactone skeleton, which shows excellent solubility with an organic solvent while holding stability such as chemical resistance when applied to a resist resin or the like, and which has high affinity to water and high solubility with water after hydrolysis, and a polymer comprising the monomer.SOLUTION: The monomer includes a carbamoyl group and a lactone skeleton represented by formula (1). In formula (1), Rrepresents H, an alkyl group having 1 to 6 carbon atoms, or the like; Rrepresents a halogen atom, an alkyl group having 1 to 6 carbon atoms which may have a halogen atom, or the like; A represents an alkylene group having 1 to 6 carbon atoms, O, S, or no bonding; m represents an integer of 0 to 8; X represents a specific carbamoyl group; n represents an integer of 1 to 9; Y represents a divalent organic group having 1 to 6 carbon atoms; and k represents 0 or 1. |
