Title: RESIN MATERIAL AND LAMINATE
Abstract:
Provided is a resin material with which it is possible to effectively improve insulating properties and thermal conductance, effectively curb variation in breakdown strength, and effectively improve adhesion. The resin material according to the present invention contains first boron nitride cohesive particles, second boron nitride cohesive particles, and a binder resin. The first boron nitride cohesive particles, when compressed from 10% to 40% of the particle diameter, generate cracking at least once as a result of compressive displacement of 5% or more of the particle diameter. The aspect ratio of primary particles that constitute the first boron nitride cohesive particles exceeds 7. The second boron nitride cohesive particles, when compressed from 5% to 75% of the particle diameter, generate cracking at least three times as a result of compression displacement of 2% or more of particle diameter. The aspect ratio of the primary particles that constitute the second boron nitride cohesive particles does not exceed 7.
