Abstract
The present invention provides with a thermal conductive sheet including a foldable layer having a bending region, a graphite sheet disposed on the foldable layer, and disposed outside the bending region, a first adhesive layer covered on the graphite sheet and the foldable layer, and a polymer film layer coated on the first adhesive layer. Accordingly, the present invention has a good heat dissipation effect, bendable and flexible in order to avoid a layer separation phenomenon.
