Zusammenfassung:	To provide a silica scale preventive that has a greater ability to inhibit silica scale than that of the conventional art and can be used suitably as an inhibitor for, for example, silica scale.SOLUTION: A silica scale preventive contains a (meth)acrylic acid copolymer that has a (meth)acrylic acid (salt)-derived constitutional unit and a sulfonic acid (salt) group-containing monomer-derived constitutional unit, wherein, relative to 100 mol% of all the monomer-derived structures, the sulfonic acid (salt) group-containing monomer-derived constitutional unit is 11 mol% or more; and the weight average molecular weight is 9200 or more.SELECTED DRAWING: None 【課題】従来よりシリカスケールの抑制能に優れることから、例えばシリカスケールの抑制剤として好適に使用することが可能なシリカスケール防止剤を提供することを目的とする。【解決手段】（メタ）アクリル酸（塩）由来の構造単位と、スルホン酸（塩）基含有単量体由来の構造単位とを含む共重合体であって、全単量体由来の構造１００モル％に対して、スルホン酸（塩）基含有単量体由来の構造単位が１１モル％以上であり、重量平均分子量が９２００以下であることを特徴とする（メタ）アクリル酸系共重合体を含むシリカスケール防止剤。【選択図】なし
