  • HEAT DISSIPATION MEMBER
    Publication number: 20210341234
    Abstract: A heat dissipation member dissipates heat generated at a heat source. The heat dissipation member may include a substrate having a porosity ratio of 5 volume % or less; and an inorganic porous layer disposed on a surface of the substrate, wherein the inorganic porous layer may have a porosity ratio ranging from 25 volume % or more to 85 volume % or less and have lower thermal conductivity than the substrate. In this heat dissipation member, 15 mass % or more of constituents of the inorganic porous layer may be alumina.
