A Ni-based alloy including chromium, cobalt, aluminum, titanium, tantalum, tungsten, molybdenum, niobium, carbon, and boron, the balance being nickel and incidental impurities, is provided. The alloy has an alloy composition of, on the basis of mass percent, chromium: 13.10% to 16.00%, cobalt: 8.00% to 12.50%, aluminum: 2.30% to 3.50%, titanium: 4.80% to 5.50%, tantalum: 0.40% to less than 1.00%, tungsten: 4.50% to 6.00%, molybdenum: 0.10% to 1.50%, niobium: 0.60% to 1.70%, carbon: 0.01% to 0.20%, boron: 0.005% to 0.02%, and the balance: nickel and incidental impurities.
