A dark color, resin sheet-like body having light reflective properties in a near-infrared region, the body comprising a surface layer (A) receiving solar radiation and a reflection layer (B). Surface layer (A) exhibits a dark color with a solar radiation absorption ratio of 90% or more in a wavelength region of 380 to 720 nm, a ratio of less than 30% in a near-infrared region of 720 to 1500 nm, and ratio of 50% or more in a near-infrared region of 720 to 1500 nm. Reflection layer (B) has a solar radiation reflection ratio of 85% or more in a wavelength region of 380 to 1500 nm. A ratio in a near-infrared region of 720 to 1500 nm of a sheet-like body formed by laminating surface layer (A) and reflection layer (B) is 70% or more.
