PRESSURE-SENSITIVE ADHESIVE MATERIAL AND THERMALLY CONDUCTIVE PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

A pressure-sensitive adhesive material contains a monomer and/or a polymer and 55 mass % or more of thermally conductive particles. The thermally conductive particles contain first thermally conductive particles having a particle size of primary particle based on volume of less than 10 μm and having a first particle size distribution and second thermally conductive particles having a particle size of primary particle based on volume of 10 μm or more and having a second particle size distribution. The first thermally conductive particles are contained in the thermally conductive particles at a ratio of 10 to 80 mass %. The second thermally conductive particles are contained in the thermally conductive particles at a ratio of 20 to 90 mass %.
