Abstract
A thermally conductive sheet precursor according to an embodiment of the present disclosure includes agglomerates in which anisotropic thermally conductive primary particles are agglomerated, an isotropic thermally conductive material different from the agglomerates and having an average particle diameter of about 20 μm or greater, and a binder resin. When a first pressure in a range from about 0.75 to about 12 MPa is applied to the thermally conductive sheet precursor, at least some the agglomerates disintegrate.
