The present invention provides a silicon-containing curable composition which contains: a specific amount of a silicon-containing polymer that is obtained by the hydrolysis-condensation of an organosilane mixture containing specific amounts of organosiloxanes represented by formula (1-1) to formula (1-5) and that has an Mw of 300-100,000; a specific amount of a prepolymer that is obtained by hydrosilylating a cyclic siloxane compound represented by formula (2) and a compound represented by formula (3-1), (3-2) or (3-3) and that has two or more Si-H groups in each molecule; a specific amount of a linear siloxane compound that has two or more carbon-carbon double bonds, each of which is reactive with an Si-H group, in each molecule; a specific amount of an organic peroxide and a specific amount of a metal catalyst; and a specific amount of a filler. In this connection, formula (1-1) to formula (1-5), formula (2), and formula (3-1) to formula (3-3) are as specifically defined in the description. |
