There is provided a crack repairing method for suppressing a crack growth in a wall portion. The crack repairing method includes an injection step in which working fluid is injected into a crack formed into a surface of the wall portion of a target object and a vibration step in which vibration is applied to the working fluid in a direction from an crack initiation portion of the crack on the surface to an inner end portion of the crack. The crack repairing method further includes a deformation step in which a cavity is generated in the working fluid by the applied vibration and compressive residual stress is generated at the inner end portion of the crack.
