PROBLEM TO BE SOLVED: To provide a safe agent for removing fungi at the joint, hardly generating a harmful gas, and capable of preventing the fungi from reattaching after the removal of the fungi. SOLUTION: The spores of the fungi are decomposed by coating or spraying a colloidal titanium oxide on a position having the emerged fungi, and the reattachment of the fungi is prevented by degrading the soap residue which cause the emergency of the fungi. The titanium oxide is preferably a colloid- shaped suspended liquid of particles having 5-100 nm particle diameters, especially 5-50 nm particle diameters.
