PROBLEM TO BE SOLVED: To provide a thermoplastic resin sheet that makes it possible to obtain a laminated glass excellent in heat insulation performance and impact resistance over a wide temperature range. SOLUTION: The maximum loss tangent measured at a measurement frequency of 10 Hz is in a temperature range of 20 to 40 ° C., and the loss tangent is within a temperature range of ± 5 ° C. from the temperature showing the maximum value is 0.3 or more. Between the first and second outer layers made of the polyvinyl acetal resin film (A), the maximum loss tangent is within the temperature range of −10 to 20 ° C. and ± 5 ° C. from the temperature showing the maximum value. A third layer on the inner side made of the polyvinyl acetal resin film (B) having a loss tangent of 0.3 or more in the temperature range, a maximum value of the loss tangent is in the temperature range of 40 to 100 ° C., and It is comprised from the multilayer resin sheet containing the inner 4th layer which consists of a polyvinyl acetal resin film (C) whose loss tangent in the temperature range of +/- 5 degreeC from the temperature which shows the maximum value is 0.3 or more Thermoplastic resin sheet.
