Provided is a curable composition having reduced flowability, wherein said composition does not spill after being applied. The curable composition contains (A) a perfluoro(poly)ether group-containing silane compound having two or more Si atoms bonded to at least one group selected from the group consisting of hydroxyl groups and hydrolyzable groups, (B) a compound (other than (A)) having at least two OR 2 groups bonded to a Si atom (in the formula, R 2 each independently are a hydrogen atom or a monovalent organic group at each occurrence) or a partial hydrolysis condensate thereof, (C) a condensation catalyst, and (D) primary filler with a primary particle size from 0.01 to 0.1 μm. |
