Provided are: a sulfonic acid derivative compound that has high absorbance with respect to light having a wavelength of 365 nm, that has high solubility in an organic solvent, and that exhibits a good acid generation rate; a photoacid generator; a resist composition; a cationic polymerization initiator; and a cationically polymerizable composition. The sulfonic acid derivative compound is represented by general formula (I) (in formula (I), X represents a linear or branched alkyl group having 1-14 carbon atoms and R represents an aliphatic hydrocarbon group having 1-18 carbon atoms, an aryl group having 6-20 carbon atoms, an aryl alkyl group having 7-20 carbon atoms, an aryl group that has 7-20 carbon atoms and that is substituted by an acyl group, an alicyclic hydrocarbon group having 3-12 carbon atoms, a 10-camphor-yl group, or the like). |
