PROBLEM TO BE SOLVED: To provide a zirconium alloy which is provided with sufficient nodular corrosion resistance and uniform corrosion resistance meeting the tendency of the elongation of the residence period of nuclear fuel in a reactor accompanying increase in the combustion degree thereof, and is suitable for a nuclear fuel cladding tube and a nuclear fuel structural member, and to provide a production method therefor. SOLUTION: The zirconium alloy having excellent corrosion resistance comprises, by mass, 0.8 to 1.4% Sn, 0.15 to 0.45% Fe, 0.05 to 0.30% Cr, 0.01 to 0.15% Ni and >0.006 to 0.020% Si, and the balance Zr with inevitable impurities, and in which the incorporation ratios of Fe, Cr and Ni satisfy the following two inequalities: 0.9≤Fe/Cr≤8 (1), and 2.5≤Fe/Ni≤25 (2).
