An object of the present invention is to provide a sulfonium salt that has sufficient photosensitivity by active energy rays, such as visible light, ultraviolet rays, electron beams, and X-rays. The present invention is a sulfonium salt represented by formula (1). It is noted that R 1 is a group represented by formula (2); R 2 and R 3 each represent an aryl group having 6 to 30 carbon atoms, a heterocyclic hydrocarbon group having 4 to 30 carbon atoms, an alkyl group having 1 to 30 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, or an alkynyl group having 2 to 30 carbon atoms; X - represents a monovalent polyatomic anion; R 4 to R 6 each represent an alkyl group, or the like; k represents an integer of 0 to 4; m represents an integer of 0 to 3; n represents an integer of 0 to 4; and A represents a group represented by -S-, -O-, -SO-, -SO 2 -, or -CO - .
