PROBLEM TO BE SOLVED: To provide a boron nitride particle having high circularity, high loose bulk density, and capable of being filled tightly.SOLUTION: The boron nitride particle has (1) equal to or more than 0.52 g/mL of loose bulk density and equal to or more than 0.65 of average circularity, the boron nitride particle is produced by, applying mechanical energy by a mechano-chemical method with respect to a scaly boron nitride, for example. |
