摘要： Provided is a production method which makes it possible to improve a filling property, with respect to a resin, of a hexagonal boron nitride powder which contains hexagonal boron nitride particles each having a low aspect ratio, while maintaining low thermal conduction anisotropy of the hexagonal boron nitride powder. A method of producing a hexagonal boron nitride powder includes disintegrating, by a means which substantially does not involve pulverization of primary particles, a hexagonal boron nitride raw material powder which contains (i) hexagonal boron nitride particles each having an aspect ratio of 1.5 to 5.0 and (ii) an aggregate that contains hexagonal boron nitride particles each having an aspect ratio of more than 5.0.
