Abstract:
Provided is a spherical aluminum nitride powder having a particle shape that is closer to sphericity. The spherical aluminum nitride powder according to the present invention, which contains a main component comprising AlN and a side component comprising a rare earth compound, is characterized in that at least 70% of particles in the powder have an outer peripheral shape having neither an angular edge part nor an uneven part in the plane projection image of individual particles.
