Abstract
A glass sheet composite includes a first glass sheet; a second glass sheet; and a liquid layer sandwiched between the first glass sheet and the second glass sheet. The glass sheet composite has a loss coefficient greater than or equal to 1×10at 25° C., and an acoustic velocity of longitudinal wave greater than or equal to 5.0×10m/s in a sheet thickness direction at 25° C. The liquid layer has a viscous coefficient of 1×10-1×10Pa·s at 25° C., and a surface tension of 15-80 mN/m at 25° C. The liquid layer contains particles whose mean particle diameter is 0.3-1 μm.
