A curable organopolysiloxane composition comprising: (A) a mercapto group-containing organopolysiloxane; (B) a compound containing in a molecule at least two groups that are at least one type of functional groups selected from a group consisting of acryloyl groups, methacryloyl groups, and epoxy groups; and (C) an amine compound that does not have a N—H bond and/or a phosphine compound that does not have a P—H bond. The composition has favorable curability even at a relatively low temperature, and forms a cured film with excellent bonding with regard to an article to be coated.
