To provide a data collection device with a simple device configuration capable of inexpensively collecting state data on a metal member in association with the positions of respective portions of the metal member.
An ultrasonic probe 11 is used for detecting surface part signals of at least two portions of a specific domain of a metal member surface. The part signals detected by the ultrasonic probe are stored in advance in a reference position storage 12 as a reference position in the specific domain of the member surface. Surface part signals and state data on respective portions of the specific domain of the member surface are detected by a state detector 13. By a verification unit 14, a surface part signal corresponding to the part signal of the reference position stored in the reference position storage 12 is associated with the reference position among the part signals on the respective portions in the specific domain of the member surface detected by the state detector 13 while position information is allocated to the specific domain on the metal member surface on the basis of the reference position. The state data are stored in a state data storage 15 in association with the position information in the specific domain on the member surface allocated by the verification unit 14.
