description	PROBLEM TO BE SOLVED: To provide a method for inhibiting scale in a water system containing a large amount of sodium ions.SOLUTION: A sodium salt scale inhibitor at least contains a sulfone group-containing polymer, whose monomer is unsaturated sulfonic acid monomer. The sulfone group-containing polymer preferably has a weight average molecular weight of 700 g/mol or more and 70,000 g/mol or less. Also preferably, unsaturated sulfonic acid monomers constituting the sulfone group-containing polymer are 3 mol% or more, when all the monomers constituting the sulfone group-containing polymer are 100 mol% in total.SELECTED DRAWING: Figure 1 【課題】多量のナトリウムイオンを含有する水系におけるスケールの発生を防止する方法を提供すること。【解決手段】本発明のナトリウム塩スケール防止剤は、少なくとも、不飽和スルホン酸系単量体を単量体とする、スルホン基含有ポリマーを含む。スルホン基含有ポリマーは、重量平均分子量が７００ｇ／ｍｏｌ以上７０，０００ｇ／ｍｏｌ以下であることが好ましい。スルホン基含有ポリマーを構成する不飽和スルホン酸系単量体のモル数が、スルホン基含有ポリマーを構成する全ての単量体のモル数の総和を１００モル％とした場合に、３モル％以上であることが好ましい。【選択図】図１
