To simply prevent sand from flowing out on rain water by continuously scattering the sand having a specific grain size larger than that of the sand scattered at the competition portion of artificial turf near a side ditch on the artificial turf ground scattered with sand on the artificial turf.

A cushion layer 3 is laid on a foundation bed layer 2 made of asphalt, artificial turf 4 planted with synthetic fiber pile threads on a synthetic fiber ground fabric 41 to form turf leaves 42 is laid, sand 5 is scattered, and pressing force is applied to form this artificial turf ground 1. Sand 5A having a grain size larger than that of the sand 5 scattered at a competition portion is scattered near a side ditch 6 continuously to the sand 5. The average grain size of the sand 5A near the side ditch 6 is set to 0.4-2.3mm while the grain size of the sand 5 at the competition portion is 0.15-0.8mm. When rain water flows down, the sand 5 having the small grain size is floated and tends to flow out, however the sand 5A arrests the sand 5 and prevents its transit. The outflow of the sand 5 by rain water can be prevented.
