A curable composition includes a blocked isocyanate in which an NCO group of an isocyanate compound having a HXDI skeleton is blocked by a blocking agent having an O&#x2550;C&#x2014;CH&#x2014;C&#x2550;O skeleton, a curable functional group-containing fluorine polymer, and an alkoxysilane having a functional group including at least one element of a group 15 element to a group 16 element of the periodic table (excluding oxygen). In the curable composition allowing a titanium oxide to be contained, the molar ratio of the curable functional group to the NCO group is 0.5 to 10; the content ratio of the alkoxysilane with respect to 100 pans by mass of the total amount of the blocked isocyanate and the fluorine polymer is 0.2 to 8 parts by mass; and the content ratio of the titanium oxide with respect to 100 parts by mass of the fluorine polymer is 0 to 200 parts by mass.
