Use of a protective net as protective net for golf, soccer, baseball, tennis or volleyball comprising meshes formed between intersections of synthetic fiber cords while the synthetic fiber cords have a form in which a plurality of plied and twisted synthetic fiber filaments are crossed in a knotless type, characterised in that the synthetic fiber filament is an aramid filament and wherein, when the protective net is used for golf, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.85 mm to 1.5 mm, maximum distance of the intersections adjacent to each other is 35 mm or less, and minimum distance of the intersections adjacent to each other is 20 mm or more; or wherein, when the protective net is used for soccer, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.59 mm to 0.84 mm, maximum distance of the intersections adjacent to each other is 140 mm or less, and minimum distance of the intersections adjacent to each other is 135 mm or more; or wherein, when the protective net is used for baseball, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.75 mm to 1.07 mm, maximum distance of the intersections adjacent to each other is 50 mm or less, and minimum distance of the intersections adjacent to each other is 40 mm or more; or wherein, when the protective net is used for tennis, diameter (d) of the synthetic fiber cord is 0.73 mm to 1.03 mm, maximum distance of the intersections adjacent to each other is 42 mm or less, and minimum distance of the intersections adjacent to each other is 38 mm or more; or wherein, when the protective net is used for volleyball, diameter (d) of the synthetic fiber cord is 0.33 mm to 0.47 mm, maximum distance of the intersections adjacent to each other is 126 mm or less, and minimum distance of the intersections adjacent to each other is 122 mm or more. characterised in that the synthetic fiber filament is an aramid filament and wherein, when the protective net is used for golf, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.85 mm to 1.5 mm, maximum distance of the intersections adjacent to each other is 35 mm or less, and minimum distance of the intersections adjacent to each other is 20 mm or more; or wherein, when the protective net is used for soccer, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.59 mm to 0.84 mm, maximum distance of the intersections adjacent to each other is 140 mm or less, and minimum distance of the intersections adjacent to each other is 135 mm or more; or wherein, when the protective net is used for baseball, the synthetic fiber cord is an aramid cord consisting of the aramid filament, diameter (d) of the aramid cord is 0.75 mm to 1.07 mm, maximum distance of the intersections adjacent to each other is 50 mm or less, and minimum distance of the intersections adjacent to each other is 40 mm or more; or wherein, when the protective net is used for tennis, diameter (d) of the synthetic fiber cord is 0.73 mm to 1.03 mm, maximum distance of the intersections adjacent to each other is 42 mm or less, and minimum distance of the intersections adjacent to each other is 38 mm or more; or wherein, when the protective net is used for volleyball, diameter (d) of the synthetic fiber cord is 0.33 mm to 0.47 mm, maximum distance of the intersections adjacent to each other is 126 mm or less, and minimum distance of the intersections adjacent to each other is 122 mm or more.
