description The invention provides high-conductivity cable steel for manufacturing a lead of a thin film capacitor. The high-conductivity cable steel comprises the following components in percentage by weight: not greater than 0.003% of C, not greater than 0.02% of Si, not greater than 0.055% of Mn, not greater than 0.015% of P, not greater than 0.007% of S, not greater than 0.005% of N and not greater than 0.01% of Alt. A method comprises the following steps of: carrying out steelmaking after molten iron is desulfurized; carrying out RH vacuum treatment; carrying out continuous casting; heating a castingblank; stacking and naturally cooling to room temperature; carrying out rough rolling; carrying out finish rolling; spinning; carrying out heat preservation; and standing by. According to the high-conductivity cable steel and the production method, the conductivity is not less than 16.9% and is improved by at least 5% in comparison with the prior art on the premise of ensuring that the tensile strength is not greater tha
