Title: RESIN MATERIAL AND LAMINATE
Abstract:
A resin material is provided which can effectively improve insulation properties, can effectively suppress variation in dielectric breakdown strength and can further effectively increase adhesion. This resin material contains first boron nitride aggregate particles, second boron nitride aggregate particles, and a binder resin. The cumulative 50% pore diameter is less than 2 µm in the volume-based pore diameter distribution of the pores in the first boron nitride aggregate particles that have a pore diameter greater than 0 µm and less than or equal to 5 µm, the cumulative 50% pore diameter is greater than or equal to 2 µm in the volume-based pore diameter distribution of the pores in the second boron nitride aggregate particles that have a pore diameter greater than 0 µm and less than or equal to 5 µm, and the aspect ratio of the primary particles constituting the second boron nitride aggregate particles is less than or equal to 7.
