To provide a synthetic resin artificial lawn with high bending resistance, flexibility, fatigue resistance, abrasion resistance, heat resistance and forming efficiency at a low cost.

An artificial lawn is constituted of a substrate section 2 and a large number of synthetic resin projected bodies 1 extended upward from the substrate section 2. Then, main ingredients of a resin composition for constituting the artificial lawn are constituted of mixture of ethylene-α-olefin copolymer having 0.900-0.940 g/cm3 of density and 1-50 g/10 minutes of melt flow rate and polyethylene having 0.910-0.935 g/cm3 of density and 0.5-30 g/10 minutes of melt flow rate, and its weight ratio is 30:70-80:20.
