| 主权项 | 1. A silicone resin sheet obtained by molding a silicone resin composition into a sheet, and then semi-curing the sheet, wherein the silicone resin composition comprises: (1) an organopolysiloxane having at least two alkenylsilyl groups in one molecule, (2) an organopolysiloxane having at least two hydrosilyl groups in one molecule, (3) a hydrosilylation catalyst, and (4) a curing retarder, wherein a hydrosilyl group functional group equivalent of the organopolysiloxane having at least two hydrosilyl groups in one molecule is 0.010 to 5 mmol/g, wherein the curing retarder contains tetraalkylammonium hydroxide, and the tetraalkylammonium hydroxide content is 10 to 500 mol relative to 1 mol of the hydrosilylation catalyst, and the silicone resin sheet is semi-cured. | ||
