PROBLEM TO BE SOLVED: To provide an artificial lawn which suppresses a rise in surface temperature by efficiently arranging lawn leaves with excellent heat shielding properties. SOLUTION: The second lawn leaves and the first lawn leaves higher in solar reflectance than the second lawn leaves are formed of the same synthetic resins, the first lawn leaves are formed in such shapes as to be wider than the second lawn leaves, and cross-sectional shapes of the first and second lawn leaves are set different from each other, so that the second moment of an area of the first lawn leaves can become smaller than that of the second lawn leaves. Since the second moment of area of the first lawn leaves is set smaller than that of the second lawn leaves, the inclination of the first lawn leaves in a rising state becomes larger than that of the second lawn leaves, a surface area for receiving sunlight becomes larger, and the sunlight is further reflected to suppress a rise in the temperature of the surface area of the artificial lawn.
