An object of the present invention is to provide an interlayer filling material for a touch panel and a touch panel laminate manufactured using the interlayer filling material for the touch panel, and the interlayer filling material for the touch panel is used in the manufacture of an action information terminal. The touch panel laminate can be obtained by filling the layers of the touch panel and other members or the plurality of transparent conductive films constituting the touch panel to obtain a surface protection panel or a glass substrate which is less likely to be cracked or broken and has no color unevenness. The interlayer filling material for the touch panel of the present invention is used for filling the interlayer of the touch panel and other members or between the layers of the plurality of transparent conductive films constituting the touch panel, the layers of the glass plate and the transparent conductive film, the glass plate and the glass plate. Between the layers, between the layers of the glass plate and the polarizing film, between the layers of the substrate and the glass plate, between the layers of the substrate and the transparent conductive film, and between the substrate and the polarizing film, the polyethylene acetal and the plasticizer are contained at 25 ° C. The residual stress Kpa (25 ° C, 2 min) after a minute was 300 kPa or less. |
