Abstract: The present invention provides a heat conducting device with permeability, comprising a heat conducting base which is a metal heat conducting base, a graphite heat conducting base, or an alloy heat conducting base, and the heat conducting base is provided with a magnetic conducting seam which extends through two surfaces in thickness direction of the heat conducting base. The heat conducting device with permeability provided in the present invention uses graphite, metals, or alloys having shielding property and excellent heat conducting property as a heat conducting base, and by opening a magnetic conducting seam on the heat conducting base to relieve the shielding effect to the signals, the heat conducting device has both excellent heat conducting property and magnetic permeability, and can be applied to electronic products that have magnetic permeability requirements, thereby promoting the development of electronic products to be ultra-thin.
