PROPERTY MEASURING DEVICE FOR OBJECT TO BE MEASURED AND PROPERTY MEASURING METHOD FOR OBJECT TO BE MEASURED
[Problem] To provide a property measuring device for an object to be measured and a method therefor, the device capable of extracting an electric signal that is a measuring object from an electromagnetic field noise generated from an acoustic wave generation source, or the like with a high degree of reliability even in the case of continuous waves while maintaining high spatial resolution by using acoustic waves as an object property measuring means. [Solution] This property measuring device (100) for an object to be measured is provided with: an acoustic wave application unit (40) which is disposed apart from an object to be measured (90) and applies amplitude-modulated acoustic waves
a receiving unit (50) which receives electromagnetic fields generated by applying the acoustic waves to the object to be measured (90)
and a measuring unit (60) which, on the basis of the measurement of at least one type selected from the group consisting of the strength, phase, and frequency of the electromagnetic fields, extracts at least one type of property selected from the group consisting of the electric property, magnetic property, electromechanical property and magnetomechanical property of the object to be measured (90).
