Heat transport properties of planetary constituent materials are indispensable information for understanding thermal evolution of solid earth planets. It is thought that the earth's core is composed of an alloy containing iron as a main component. The key physical quantity for the quantitative evaluation of the electron transport is the strength of electron-phonon interaction that is a major heat transport mechanism in metals. In this study, we calculated the electron lifetime and total electron-phonon coupling constants associated with the electron-phonon scattering for the hexagonal close-packed iron considered to be the major constituent mineral of the earth’s inner core. The electric and thermal conductivities were then determined under the earth’s inner core conditions.
