PROBLEM TO BE SOLVED: To obtain a highly heat-conductive composition fluidizing at a specified temperature, excellent in heat radiation and low in heat resistance, and to provide a radiating member capable of microscopically adhering to the respective surfaces to be joined of exothermic electronic parts and radiating fins. SOLUTION: The heat-conductive composition is characterized in that it is a mixture of wax and/or paraffin with the melting point at 40-100 deg.C, a thermoplastic resin softening at 40-100 deg.C, and spherical alumina having a sphericity of 0.78 or higher and an average grain diameter of 3 μm or more. A radiating member fox exothermic electronic parts and an exothermic electronic part structure integrated with radiating fins are provided by suing this composition. |
