Provided is a flame retardant silicone resin sheet (100) which exhibits high flame retardancy, is unlikely to sustain surface scratches, and is unlikely to crack even when bent. Also provided is an adhesive layer-equipped flame retardant silicone resin sheet (1000), which has this type of flame retardant silicone resin sheet (100) and an adhesive layer (200). Also provided is a substrate layer-equipped flame retardant silicone resin sheet (2000), which has this type of flame retardant silicone resin sheet (100) and a substrate layer (300). This flame retardant silicone resin sheet (100) is formed from a silicone resin composition containing a silicone resin and a glass frit. The pencil hardness, as specified in JIS K5600-5-4: 1999, of a surface of the flame retardant silicone resin sheet is F or harder.
