PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding material which has a practically sufficient electromagnetic wave shielding performance and durability, and is very useful for many uses necessary for a characteristic of flexibility. SOLUTION: The electromagnetic wave shielding material is composed of conductive polyvinyl alcohol fibers, as main fibers, made of polymer of polyvinyl alcohol and particles of copper sulfide of a mean diameter of particle of 500 nm or less, and including the particle of copper sulfide on a surface layer and/or the inside of the fibers. The fiber shields electrical field component of electromagnetic wave of 100 MHz by 20 dB or more. COPYRIGHT: (C)2007,JPO&INPIT
