  • Publication number: 20100116543
    Abstract: An electromagnetic wave suppression sheet (1) includes moisture-resistant films (11a), (11b) and an acrylate based polymer gel containing x wt % of an alcohol. The electromagnetic wave suppression sheet (1) is formed by molding so that its thickness (t2) y in mm will be in a region formed by interconnecting a point a (10, 1.0), a point b (10, 3.0) and a point c (20, 1.0), totaling at three points, in an xy coordinate system (x, y). This yields a high non-freezing properties and a high incombustibility of the sheet.
