[PROBLEMS] To be used for filling an interlayer between a touch panel and another member or between a plurality of transparent conductive films constituting the touch panel in the manufacture of a portable information terminal, etc., and the surface protection panel or the glass substrate is cracked or damaged. Provided is an interlayer filling material for a touch panel that can obtain a touch panel laminate that is difficult and has no color unevenness, and a touch panel laminate that is manufactured using the interlayer filling material for a touch panel. An interlayer between a touch panel and another member, an interlayer between a plurality of transparent conductive films constituting the touch panel, an interlayer between a glass plate and a transparent conductive film, an interlayer between a glass plate and a glass plate, a glass plate and a polarizing film, Interlayer filling material for touch panel used to fill the interlayer between the substrate and the glass plate, between the substrate and the transparent conductive film, between the substrate and the polarizing film, and contains polyvinyl acetal and plasticizer An interlayer filling material for a touch panel having a residual stress Kpa (25 ° C., 2 min) after 2 minutes at 25 ° C. of 300 kPa or less.
