Zusammenfassung:	To solve the problem that a silver plated contact point using copper and a copper alloy material as a base material is used in an on-board switch and a connector, and local electric conductivities are varied and abrasion resistance is low.SOLUTION: There are provided a copper-alloy composite foil in which at least one surface of a copper alloy plate is subjected to silver plating controlling crystal orientation; and a copper-alloy composite foil which varies crystal orientation by subjecting the copper-alloy composite foil to rolling treatment, and is excellent in abrasion resistance.SELECTED DRAWING: Figure 3 【課題】車載スイッチやコネクタには母材に銅及び銅合金材を使用した銀めっき接点が使用されているが、局所的な電気伝導度がばらついたり、耐摩耗性が低いことなどの問題があった。【解決手段】銅合金板の少なくとも片方の表面に結晶配向を制御した銀めっきを施した銅合金複合箔及びこの銅合金複合箔を圧延処理することにより結晶配向を変化させた耐摩耗性に優れた銅合金複合箔を得ることができる。【選択図】図３
