Abstract
Provided is a resin material capable of effectively improving the insulating properties and the thermal conductivity, and effectively controlling the variation in dielectric breakdown strength. A resin material according to the present invention includes first boron nitride aggregate particles, second boron nitride aggregate particles, and a binder resin, and a 10% K value of the second boron nitride aggregate particles is smaller than a 30% K value of the second boron nitride aggregate particles, and a 30% K value of the second boron nitride aggregate particles is smaller than a 10% K value of the first boron nitride aggregate particles.
