The mildew-removing, mildew-proofing and bactericidal agent preferably contains 0.1-1.0 mass% (preferably 0.1-0.6 mass%) of sodium chloride. Furthermore, the silver ions are preferably fed from a silver compound (Ag<SB>2</SB>O etc.) contained in a resin molded product (composed of polyethylene resin etc.) in contact with the electrolyzed water. The saponin is preferably saponin obtained by extracting bark of Quillaja saponaria which is a plant of the family Rosaceae. COPYRIGHT: (C)2008,JPO&INPIT
