Abstract: An ammonium salt having a saccharin anion, which is represented by formula (1), exhibits excellent thermal stability even though no halogen atom is contained therein. (In the formula, each of R1-R4 independently represents an alkyl group having 1-4 carbon atoms or an alkoxyalkyl group that is represented by —(CH2)n—OR (wherein R represents an alkyl group having 1-4 carbon atoms, and n represents an integer of 1 or 2). Incidentally, any two of the R1-R4 may combine with each other to form a ring together with a nitrogen atom.
