A process for producing a copper alloy strip having an excellent balance among all of tensile strength, elongation, and electrical conductivity. The process comprises: a step in which a copper-nickel-phosphorus type copper alloy is hot-rolled and then subjected to aging precipitation to obtain a copper alloy strip which has undergone the aging precipitation; a step in which the copper alloy stripwhich has undergone the aging precipitation is subjected to intermediate cold rolling at a reduction ratio of 50-90% and then subjected to an intermediate recovery heat treatment to obtain a copper alloy strip which has undergone the recovery heat treatment; and a step in which the copper alloy strip which has undergone the recovery heat treatment is subjected to final cold rolling at a reductionratio of 20-95% and then subjected to a final recovery heat treatment to obtain a copper alloy strip based on a recovery phenomenon. In this process, by regulating the combination of cold rolling andrecovery heat treatment conditions, a precipitation-hardened copper alloy strip having properties in target ranges can be produced.
