PROBLEM TO BE SOLVED: To provide an algae outgrowth inhibitor and an algae outgrowth suppressing method in which maintenance is easy or unnecessary and versatility is high, and which is cheap. SOLUTION: The algae outgrowth inhibitor controls outgrowth of algae on a surface of goods, comprises making (a) a silicon-containing compound expressed by general formula (1), wherein R<SP>1</SP>represents a hydrocarbon having a carbon number of 6 or more, R<SP>2</SP>and R<SP>3</SP>show a lower hydrocarbon group which may be the same or different, R<SP>4</SP>shows a bivalent lower hydrocarbon group, R<SP>5</SP>, R<SP>6</SP>and R<SP>7</SP>show a lower alkyl group or a lower alkoxy group which may be same or different, X shows a halogen ion or an organic carbonyloxy ion, uniformly disperse in water by (b) at least one surfactant chosen from a group consisting of a cationic surfactant (however, excluding the silicon compound) (b1), a nonionic surfactant (b2), and an ampholytic surfactant (b3).
