Abstract(in English) A threat of leakage of sound information via electromagnetic field from a smart device having an audio output function has been reported. To suppress leakage of sound information through EM waves, it is useful to search frequency bands that propagate sound information and electrical components that cause leakage of audio information. However, there is not enough discussion about the electrical components causing information leakage. In this paper, to provide the fundamental knowledge necessary to suppress leakage, we measure the EM field including audio information radiated from the components of the device and create cartography relating to the intensity of the radiated EM field. Thereby, we are able to find out the part causing information leakage. Finally, we verify the leakage source by extracting component and measuring EM waves from the component.
