PROBLEM TO BE SOLVED: To provide a property evaluation device and a property evaluation method that can evaluate properties of an electrical steel sheet nondestructively and contactlessly with high spatial resolution, and to provide a manufacturing method for the electrical steel sheet and a manufacturing system for the electrical steel sheet based upon the evaluation result.SOLUTION: A property evaluation device 100 as one embodiment of the present invention comprises: a sound wave generation part 20 which irradiates an electrical steel sheet 90 with a sound wave; a magnetic field application part which applies the electrical steel sheet 90 with a magnetic field having a magnetic field intensity larger than zero and less than a value large enough to cause the electrical steel sheet 90 to get magnetically saturated; and a reception part 40 which receives an electromagnetic wave generated by the electrical steel sheet 90 with the sound wave. In this property evaluation device 100, the sound wave generation par
