Defect analyzers, defect analysis method, and program

Providing a defect analyzing apparatus for improving the accuracy of locating the pipe (1) which is formed in the leakage hole (3). The defect analyzer, a phase shift of the first vibration detection unit due to the installation environment of the first vibration detection unit (20A) (20A) is generated in the vibration data to detect, and, second vibration detection parts in consideration of an error caused by the deviation of the phase of the second vibration detection unit due to the installation environment (20B) is generated in the vibration data to detect the (20B), formed in the pipe (1) identifying the location of the leakage hole (3).
