A general heat conduction law can be derived from the thermomass theory, and it is applicable under the ultra-high heat flux and ultra-fast laser heating conditions. The state equation for phonon gas has been obtained based on the thermomass theory in the past, leading to the general heat conduction law in dielectrics. However, electrons are the main energy carriers in metals and the sate equation for phonon gas is no longer available. The sate equation for thermomass in electron gas has been derived in this paper and the corresponding general heat conduction law has been obtained. It gives the theoretical foundation of the study of non-Fourier behaviors in metals under the extreme conditions.
