1. A method for producing silicon-containing oxide-coated aluminum nitride particles comprising aluminum nitride particles and a silicon-containing oxide coating covering a surface of each of the aluminum nitride particles, the method comprising:
a first step comprising mixing aluminum nitride particles and an organic silicone compound solution consisting of an organic silicone compound having a structure represented by formula (1) below and a solvent to form a mixture consisting of the aluminum nitride particles, the organic silicone compound and the solvent and then heating the mixture to remove the solvent and to obtain aluminum nitride particles coated with the organic silicone compound; and
a second step comprising heating the aluminum nitride particles coated with the organic silicone compound at a temperature of 300° C. or more and 1,000° C. or less,
