The present invention provides an interlayer filling material for a touch panel which is used for filling in between the layers of a touch panel and another member in the manufacture of a portable information terminal or the like, and which conforms well to steps in wiring or steps in a decorative printing part when filling (bonding) is performed, is excellent with respect to the ability to release trapped air bubbles or air bubbles remaining in the vicinity of a step when filling (bonding) is performed, and reduces the scattering of shards when the portable information terminal is damaged. In addition, the objective is to provide a laminated body manufactured using this interlayer filling material for a touch panel. The present invention is an interlayer filling material for a touch panel and is used for filling in between the layers of a touch panel and another member, said interlayer filling material containing plasticized polyvinyl acetal and having a storage modulus (G') (20) of 2×105Pa or greater at 20°C, a storage modulus (G') (85) of 1×106Pa or less at 85°C, and the temperature (Tg) between -20°C and 100°C at which tanδ is the maximum value is 5-85°C. |
