As shown in FIG. 1, the copper matrix phases and the composite phases form a matrix phase-composite phase layered structure and are arranged alternately parallel to a rolling direction as viewed in a cross-section perpendicular to the width direction. In addition, the copper-zirconium compound phases and the copper phases in the composite phases form a composite phase inner layered structure and are arranged alternately parallel to the rolling direction at a phase pitch of 50 nm or less as viewed in the above cross-section. This double layered structure presumably makes the copper alloy foil densely layered to provide a strengthening mechanism similar to multilayer reinforced composite materials.
