Electromagnetism suppressing material, electromagnetism suppressing device, and electronic appliance

Abstract

An electromagnetism suppressing material has an increased electromagnetism suppressing effect, can be flexibly formed in various shapes, and is inexpensive. An electromagnetism suppressing device uses the electromagnetism suppressing material, and an electronic appliance uses the electromagnetism suppressing material or the electromagnetism suppressing device. The electromagnetism suppressing material is a liquid material and/or gel material with electrical polarity.
