To provide a blade 6 for an axial flow compressor prevented from damage due to resonance with a fluid vibrating force by selectively increasing a stripe natural frequency 19 of the blade 6 for the axial flow compressor.

In this blade 6 for the axial flow compressor, when a cross section having a maximum thickness 10 smaller than that of a blade tip part 11 cross section is decided to the thickness 10 of the intermediate part 13 in the blade height 12 direction, the stripe natural frequency 19 is increased higher than that of a conventional blade, and consequently, resonance with a fluid vibrating force can be avoided.
