Abstract
An object of the present invention is to provide an insulation sheet having high thermal conductivity in the in-plane direction. The present invention provides an insulation sheet comprising insulating particles and a binder resin, wherein, for the entire cross-section of the sheet perpendicular to the in-plane direction, the insulation sheet contains 75 to 97% by area of the insulating particles, 3 to 25% by area of the binder resin, and 10% by area or less of the voids.
Claims14
An insulation sheet comprising insulating particles and a binder resin,
- wherein, for the entire cross-section of the sheet perpendicular to the in-plane direction, based on 100% by area of the total of the insulating particles, the binder resin and voids, the insulation sheet contains 75 to 97% by area of the insulating particles, 3 to 25% by area of the binder resin, and 10% by area or less of the voids,
- wherein the insulating particles comprise flat-shaped particles that are deformed.
