Apparatus for displaying the distribution of an electric property of an electronic appliance

An electronic appliance displaying apparatus that, by implementing the following views, makes it possible to identify a wire, a component, or the like that generates an electromagnetic field. At first, the displaying apparatus derives electric-current distribution (203), electric-voltage distribution, electric-power distribution, or impedance distribution from magnetic-field distribution or electric-field distribution existing in vicinities of an electronic appliance, i.e., a target to be measured. Next, the displaying apparatus superposition-displays (201,601,1201) at least one of the above-described distributions on an image of the electronic appliance, CAD data thereon, layout data thereon, or circuit diagram thereof (202,502,1102). Otherwise, the displaying apparatus displays, on plural views (301,801,1401), at least one of the distributions and the latter data (202,502,1102).
