Abstract (in Japanese) (See Japanese page) 
(in English) In the midst of technological progress in 5G, automatic driving, and wireless power supply, CAD (Computer Aided Design) and design environment facilities have been enhanced, but opportunities to work on EMC (Electro-Magnetic Compatibility) measures, which are essential for practical design measures, have been decreasing. Therefore, it is very important to learn practical techniques through a series of experiences of conceptual design, product manufacturing, and EMC design for product realization. In this paper, the CISPR25 radiated emission ALSE method test is followed, and a product is fabricated using Arduino in the range of 30MHz-1000MHz, the noise sources are identified, and countermeasure techniques are investigated. As a result, bypass capacitors, ferrite cores, and twisted wires are used as countermeasures, and as a result, more than 20 dB of attenuation of radiated noise is confirmed in a wide frequency range.
