Silicone-laminated substrate, including glass cloth, and cured product of silicone resin composition—with which the glass cloth is filled and a surface of the glass cloth is coated. The silicone resin composition includes: (A) an organopolysiloxane having a resin structure of specific siloxane units, (B) an organohydrogenpolysiloxane having a resin structure of specific siloxane units, (C) a platinum group metal-based catalyst, and (D) a filler. The silicone-laminated substrate exhibits excellent mechanical properties, flexibility and workability, has minimal surface tack, and is easy to handle. The silicone-laminated substrate is produced by impregnating a glass cloth with the silicone resin composition dissolved or dispersed in a solvent, subsequently evaporating the solvent from the glass cloth, and subjecting the composition impregnated into the glass cloth to heat-curing under compression-molding conditions. Also, an LED device which includes the silicone-laminated substrate and an LED chip mounted on top of the substrate.
