Abstract

See full text

It is an object to achieve a resin sheet having high thermal conductance and high dielectric strength. Hexagonal boron nitride powder in accordance with an aspect of the present invention includes hexagonal boron nitride agglomerate particles each including agglomerated hexagonal boron nitride primary particles, and has a specific surface area of not less than 0.5 m2/g and not more than 5.0 m2/g. The hexagonal boron nitride primary particles each have a long diameter of not less than 0.6 μm and not more than 4.0 μm and an aspect ratio of not less than 1.5 and not more than 5.0.
