A thermal conductive material having excellent thermal conductivity, adhesiveness, heat resistance, and electrical insulation, an adhesive sheet having a thermal conductive material layer made of the thermal conductive material, and the thermal conductive material are used. Provided lighting fixtures. A thermally conductive material containing plate-like particles and an adhesive resin as essential components, containing spherical particles in an amount of 500 parts by mass or less per 1 part by mass of plate-like particles, and containing an adhesive resin (solid Min) The total amount of plate-like particles and spherical particles per 100 parts by mass is 1 to 600 parts by mass, and at least one of the thermally conductive material layer made of the thermally conductive material A lighting device having a pressure-sensitive adhesive sheet on the surface, a substrate 2 on which the light-emitting element 1 is mounted, and a radiator 4, and the heat conduction made of the thermally conductive material between the substrate 2 and the radiator 4. An illuminating device, characterized by interposing a conductive material layer 3. [Selection] Figure 1 |
