A thermal conductive sheet with conductive foil is obtained by press bonding a magnetic foil to a thermal conductive layer via a primer layer. Since the primer layer contains a thermal conductive filler, it has high thermal conductivity and does not interrupt thermal conduction from the thermal conductive layer to the magnetic foil. It also spontaneously destroys a skin layer on the surface of the thermal conductive layer upon the press bonding. Accordingly, the thermal conductive sheet with conductive foil of the present invention improves thermal conduction from the thermal conductive layer to the conductive foil, eliminating the unfavorable effects of the skin layer and the primer layer, and thus improves heat radiation of the thermal conductive sheet with conductive foil.
A thermal conductive sheet comprising a thermal conductive layer press bonded to a conductive foil via a primer layer into which a thermal conductive filler in the form of powder, chop, whisker or fiber is mixed.
