An objective of the present invention is to provide a curable silicone composition of the present invention exhibiting superior adhesive properties with respect to a poor-adhesive resin such as PPS, even if the composition is cured at a relatively low temperature for a short period. The aforementioned objective of the present invention is achieved by a curable silicone composition comprising: (A) an organopolysiloxane having at least two alkenyl groups in a molecule, (B) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule, (C) a hydrosilylation-reaction catalyst, and (D) an acid anhydride having an alkoxy group bonding to a silicon atom or an alkoxyalkoxy group bonding to a silicon atom.
