PROBLEM TO BE SOLVED: To provide a zirconium alloy provided with sufficient uniform corrosion resistance, small in hydrogen absorbency and suitable for a nuclear fuel cladding pipe and nuclear fuel structural member and to provide a method for producing the same. SOLUTION: This zirconium alloy has a composition containing, by mass, 0.3 to 1% Sn, 0.1 to 0.4% Fe, 0.05 to 0.15% Cr, 0.2% or less Ni, 0.03 to 0.5% Cu, 0.03 to 0.5% Ta, 0.008 to 0.02% Si, and the balance Zr with impurities, and in which the contents of Cu and Ta also satisfy 0.1<=Cu+Ta<=0.45, and a method for producing the same is provided.
