The present invention provides a laminated sheet having a good color tone, good infrared shielding properties, and excellent weather resistance. The present invention relates to a laminated sheet (10X) including surface layers (12A, 12B) containing a methacrylic resin laminated on at least one surface of the substrate layer (11) containing a polycarbonate resin. The substrate layer (11) contains a colorant. The total thickness is 3.0 to 10.0 mm, and T1 > T2 is satisfied wherein T1 represents the thickness of the substrate layer (11) and T2 represents the total thickness of the surface layer (12A, 12B). The total light transmittance is 3 to 60%, and the transmittance at a wavelength of 1,500 nm is 60% or less. The absolute value of a* value is 10.0 or less and the absolute value of b* is 10.0 or less in the L*a*b* color space defined by JIS Z 8781-4.
