PROBLEM TO BE SOLVED: To obtain a safe antifoulant for underwater members having excellent antifouling effects on aquatic damaging organisms including coelenterate and shellfishes, Polychaeta living in pipes and algae sticking on culturing or stationary fishnets, and the like, having high storage stability with low-polluting tendency, and slight in environmental burden as well. SOLUTION: The antifoulant for underwater members that enables the surfaces of the underwater members to be imparted with antifoulingness by applying it to the surfaces of the members used by immersing underwater comprises a phenolic oligomer obtained by reaction between a phenolic compound and an alkenyl aromatic hydrocarbon in the presence of an acid catalyst.
