A heat dissipation member having high thermal conductivity and a sheet thereof are provided. In a sheet-like heat radiating member comprising a resin and an anisotropic inorganic powder, anisotropic inorganic particles are oriented in the sheet thickness direction, and X-rays are emitted from the sheet-like heat radiating member. The peak ratio of the <002> plane to the <100> plane (<002> / <100 in the X-ray diffraction diagram obtained by irradiation in the sheet thickness direction at an angle of 90 ° with respect to the sheet length direction. >) Is 10 or less. A heat radiating member in which the inorganic powder having anisotropy is one or more selected from the group consisting of boron nitride, graphite, and metal powder processed into a scale shape or a plate shape.
