Insulating sheet and laminate

Abstract

Provided is an insulating sheet capable of effectively enhancing thermal conduction and adhesiveness and effectively suppressing generation of voids. The insulating sheet according to the present invention contains a thermosetting component and boron nitride, the insulating sheet has a first surface on one side in a thickness direction and a second surface on the other side in the thickness direction, and a first average major diameter of the boron nitride in a region having a thickness of 10% of a thickness of the sheet, from the first surface toward the second surface is smaller than a second average major diameter of the boron nitride in a region having a thickness of 90% of a thickness of the sheet, from the second surface toward the first surface.
