Abstract (in Japanese) (See Japanese page) 
(in English) The electromagnetic field in the intermediate frequency band (300 Hz–10 MHz) emitted from wireless power transfer (WPT) systems for electric vehicles is relatively strong, and thus human exposure assessment for these systems is required. We have developed an optical electric-field probe calibration method to measure the electric field at 85 kHz in a tissue-equivalent liquid. In this study, we evaluated the uncertainty of the calibration method to ensure the reliability of the calibration. The expanded uncertainty of the calibration method is about 10%. In addition, we analyzed the dominant uncertainty source. From this analysis, the dominant source is the probe position of the z-axis, the uncertainty of which is about 4%. We found that the sources with high uncertainty, including the probe position of the z-axis, are related to the electric field degradation.
