<p>Provided is a thermally conductive material with excellent thermal conductivity, adhesion properties, heat resistance, and electrical insulating properties; an adhesive sheet having a thermally conductive material layer comprising the thermally conductive material; and a lighting device that uses the thermally conductive material. The thermally conductive material contains sheet shaped particles and adhesive resin as required components and is characterized in that it contains spherical particles at a volume of less than or equal to 500 parts by mass per one part by mass of sheet shaped particles and that the combined volume of sheet shaped particles and spherical particles is 1-600 parts by mass per 100 parts by mass of adhesive resin (solid content). The adhesive sheet, on at least one surface thereof, has a thermally conductive material layer comprising the thermally conductive material. The lighting device has a substrate (2) upon which is mounted a light emitting element (1), and a condenser (4), and is characterized in that the thermally conductive material layer (3) comprising the thermally conductive material is interposed between the substrate (2) and the condenser (4).</p> |
