PROBLEM TO BE SOLVED: To provide an artificial lawn excellent in both wear resistance and flexibility by constituting at least the leaf part of the artificial lawn from a polyamide resin containing a polyethylene copolymer having a straight chain side chain obtained by copolymerizingα-olefin. SOLUTION: After a T-die film or inflation film is formed by use of a polyamide resin, ethylene-α-olefin copolymer of a straight chain low density polyethylene copolymer is added in order to facilitate slitting or splitting, instead of the addition of a low density polyethylene which was used in the past. The ethylene-α-olefin copolymer is formed of a polymer having a structure in which the part ofα-olefin is suspended from the side chain of polyethylene straight chain form, which exhibits excellent characteristics of environmental stress crack resistance, shearing strength, impact strength, and cold resistance, compared with both low density polyethylene and high density polyethylene.
