PROBLEM TO BE SOLVED: To provide a laminated sheet in which the occurrence of cracking due to stress acting as a result of thermal load, moisture absorption load and mechanical load during production process and handling can be suppressed.SOLUTION: There is provided the laminated sheet comprising a low-dielectric resin and a base material. In the laminated sheet, (1) the dielectric loss tangent of the laminated sheet at 10 GHz is 0.007 or more (cavity resonance method), (2) the metal foil peel strength of the laminated sheet with a metal foil that has a surface with a surface smoothness Rz of 2.0 μm or less is 0.6 N/mm or more, (3) the coefficient of linear thermal expansion of the laminated sheet (Tg or less) is 20 ppm/K or more and 60 ppm/K or less, and (4) the peel strength between the low-dielectric resin and the base material is 0.8 or more and 1.8 or less times the metal foil peel strength. |
