An object of the present invention is to provide a curable composition excellent in on-site formability, excellent in heat resistance, chemical resistance and oil resistance, and low in compression set. The invention relates to a curable composition comprising (a) a vinyl-based polymer containing at least one (meth)acryloyl group in a molecule thereof and having a number average molecular weight of 500 to 1,000,000, (b) an ethylenic unsaturated group-containing compound, (c) a thixotropic property-imparting agent, (d) fumed silica surface-treated with a (meth)acryloyl group-containing silane and (e) a photopolymerization initiator. |
