摘要: PROBLEM TO BE SOLVED: To provide a reflective film laminate that has high reflectance, excellent alkali resistance and hot-water resistance, can keep reflectance even when exposed to alkaline environment or immersion environment, with good productivity at low cost.SOLUTION: A is formed on substrate, includes, in order from the substrate side, an Al-Mg alloy containing 10-20 atom% of Mg as first layer, metal oxide 80 more Zr second layer. The thickness layer 1.0-5nm.
