A heat-resistant silicone resin composition contains a silicone resin and a heat resistance improver. The heat resistance improver is an organic polycyclic aromatic compound having one or more secondary amino groups and one or more ketone groups in a ring structure. The organic polycyclic aromatic compound maybe, e.g., quinacridone (P.V. 19) represented by the following Chemical Formula 2. A silicone resin composite material of the present invention includes the heat-resistant silicone resin composition and at least one filler selected from the group consisting of an inorganic filler and an organic filler. The at least one filler is contained in the heat-resistant silicone resin composition. Thus, the silicone resin composition and the silicone resin composite material have high heat resistance.
