    • PROBLEM TO BE SOLVED: To provide a copper alloy sheet with a deformed cross-section whose thickness is different to the sheet width direction by producing a flat sheet having a fixed thickness to the sheet thickness direction from an ingot, and subjecting the flat sheet to cold rolling with deformed rolls, which has high heat resistance, high electric conductivity and excellent bending workability without performing annealing at all in the process or at the final stage of the cold rolling with the deformed rolls.
      SOLUTION: A copper alloy having a composition comprising, by mass, 0.03 to 0.3% Fe and 0.01 to 0.1% P in such a manner that Fe/P as the mass ratio between Fe and P is controlled to 2.0 to 4.0, and also comprising 0.005 to 0.5% Sn, and the balance copper with inevitable impurities is used. If required, the copper alloy contains 0.005 to 0.5% Zn. In cold rolling by deformed rolls, the cold working ratio for a thin part is controlled to 30 to 90%.
