Abstract
A method of manufacturing a silicon-containing oxide-coated aluminum nitride particle; a method of manufacturing a heat dispersing resin composition containing the silicon-containing oxide-coated aluminum nitride particle; and the silicon-containing oxide-coated aluminum nitride particle. The method of manufacturing includes: a first step of covering the surface of the aluminum nitride particle with an organic silicone compound including a specific structure; and a second step of heating the aluminum nitride particle covered with the organic silicone compound at a temperature of 300° C. or more and less than 1000° C., wherein the content of carbon atoms in the silicon-containing oxide-coated aluminum nitride particle is less than 1000 ppm by mass.
