<p>The present invention relates to a copper alloy for electric and electronic device, a copper alloy sheet for electric and electronic device, a conductive component for electric and electronic device, and a terminal. The copper alloy for electric and electronic device comprises more than 2.0 mass% and less than 23.0 mass% of Zn; 0.10 mass% to 0.90 mass% of Sn; 0.05 mass% to less than 1.00 mass% of Ni; 0.001 mass% to less than 0.100 mass% of Fe; 0.005 mass% to 0.100 mass% of P; and a balance including Cu and unavoidable impurities, in which 0.002‰¤Fe/Ni<1.500, 3.0<(Ni+Fe)/P<100.0, and 0.10<Sn/(Ni+Fe)<5.0, are satisfied by atomic ratio, the H content is 10 mass ppm or less, the O content is 100 mass ppm or less, the S content is 50 mass ppm or less, and the C content is 10 mass ppm or less.</p> |
