Abstract
A curable silicone composition comprising 100 parts by weight of polyorganosiloxane containing at least 2 vinyl radicals bonded to silicon atom(s) in the molecule 0.1-10 parts by weight of polyorganohydrogensiloxane containing more than 2 hydrogen atoms bonded to silicon atom(s), on the average, in the molecule, 5-500 parts by weight of fine powder of a transition metal, and a catalytic amount of a platinum catalyst containing no halogen atoms in the molecule.
