PROBLEM TO BE SOLVED: To provide a room-temperature-curable sealing material which is excellent in weatherability, resistance to surface stain, and coatability. SOLUTION: A fluorocopolymer comprising 20-70 mol% fluoroolefin-derived polymerization units, 1-80 mol% polymerization units having photocurable functional groups, and 0-70 mol% other polymerization units is added to a polymer selected from among silicone polymers, (modified) polysulfide polymers, acrylic urethane polymers, soft fluoropolymers, and saturated hydrocarbon polymers having reactive silicon groups or is added to a sealing material containing the above polymer.
