Abstract
A measurement device applies a pulse current or a current of a plurality of frequencies to a laminated body having a plurality of layers having different electrical conductivities. The device acquires in-plane distribution information indicating distribution of a magnetic field of a first plane outside the laminated body. A processor generates three-dimensional magnetic field distribution information indicating a three-dimensional distribution of magnetic field on an outside of the laminated body based on the in-plane distribution information, and generates information on an inside of the laminated body by processing the three-dimensional magnetic field distribution information on the outside of the laminated body. The in-plane distribution information includes information indicating response characteristics to a change in the current applied by the current applying unit. In addition, the three-dimensional magnetic field distribution information on the outside of the laminated body includes frequency characteristics of the magnetic field.
