<p>Provided is a curable composition which exhibits excellent curability, adhesiveness and storage stability and which does not necessitate an organotin-type catalyst and is therefore highly safe. A curable composition comprising (A) an organic polymer which contains on average 0.8 or more crosslinking silicon group in one molecule and in which the main chain is not a polysiloxane, (B) a silane compound obtained by reacting a specific epoxysilane compound with a specific aminosilane compound at a ratio such that the amount of the epoxysilane compound is 1.5 to 10mol relative to one mol of the aminosilane compound, and (C) a specific titanium catalyst, with the amounts of the silane compound (B) and the titanium catalyst (C) being 0.1 to 40 parts by mass and 0.1 to 40 parts by mass respectively relative to 100 parts by mass of the organic polymer (A).</p>
