The invention provides copper alloy for electrical and electronic components, and a method for producing the same, wherein a simplified copper alloy manufacturing method is provided and the copper alloy for electrical and electronic components is excellent in strength, electric conductivity and electrical-resistance. The copper alloy contains 2.1-2.6% of Fe by weight, 0.015-0.15% of P by weight, 0.05-0.20% of Zn by weight, and the rest is composed of Cu and unavoidable impurities. In a Fe precipitate dispersed in a Cu master phase, the Fe precipitate with the single area thereof to be within the range of 20 nm2-200 nm2 and the total area of the Fe precipitate is over 0.4 % relative to the whole area of the Cu master phase. When the single area thereof to be within the range of over 200 nm2, the total area of the Fe precipitate is 0.4 < = s1/ s2 < = 1 relative to the whole area of the Cu master phase. |
