Abstract: A boron nitride powder that is an aggregate of boron nitride particles, wherein, when each of 20 boron nitride particles A that are selected from the boron nitride powder is crushed, a ratio of an average value Y (μm) to an average particle diameter X (μm) is 0.20 or more, wherein each of 20 boron nitride particles A is crushed by gradually applying a load at a loading rate of 0.7 mN/second in an arbitrary direction, the average particle diameter X (μm) is an average particle diameter of the boron nitride powder before applying the load, and the average value Y (μm) is displacement amounts in the direction of the boron nitride particles A until crushing.
