The invention discloses electrode steel with high thermal conductivity and a production method thereof, and the electrode steel comprises the following chemical components in percentage by weight: 0.001%-0.003% of C, 0.0008%-0.0012% of Si, 0.006%-0.008% of Mn, less than or equal to 0.005% of P, less than or equal to 0.003% of S, 3.8%-4.2% of Cu, 0.0004%-0.0008% of O and the balance of Fe and other inevitable impurities. The production method comprises the steps of molten iron desulphurization, converter smelting, LF furnace refining, RH vacuum treatment, billet continuous casting, heating furnace heating, rolling and cooling. The high-heat-conductivity electrode steel has the high heat conductivity coefficient, the heat conductivity coefficient of the surface layer is higher than that of the core part, heat dissipation of materials is facilitated, the heat dissipation efficiency can be effectively improved in the electrolytic aluminum process, the working temperature and resistance of the electrode steel are
