PROBLEM TO BE SOLVED: To provide an axial flow turbo-machine capable of reducing vibrational stress by an alternating current of an upstream side blade even to a stripe mode of vibrating the front edge and the rear edge in the same direction. SOLUTION: For attaining the purpose, in this axial flow turbo-machine for constituting a step by an upstream side blade 5 and a downstream side blade 4, an interval of the alternating current of the upstream side blade 5 viewed in the blade width direction of the blade tip 8 of the downstream side blade 4, is constituted in a range of 0.45-0.55 time to a blade width L of the blade tip 8 of the downstream side blade 4.
