PROBLEM TO BE SOLVED: To provide a long floor material formed of a polyolefin resin, which is free from occurrence of bulging, i.e., formation of cavities between the floor material and a floor substrate after mounting the former on the latter, and comprehensively has abrasion resistance, scratch resistance, stain resistance, and flexibility which are properties required for the long floor material. SOLUTION: The long floor material is formed of a synthetic resin composition containing synthetic resins A to C of 100 pts.wt. in total at the following composition ratio, a thickener of 1 to 15 pts.wt., and a filler of 150 to 500 pts.wt. The synthetic resin A is formed of a polyethylene resin and/or an ethylene-α- olefin copolymerized resin having a density of 0.95 or less, an MI value of 10 g/10 min or less, and a flexural rigidity of 5,000 kgf/cm<2> or less, while being contained in the synthetic resin composition in a range of 30 to 60 pts.wt. The synthetic resin B is formed of a soft polyethylene resin having an MI value of 30 g/10 min or less and containing a comonomer of 30 wt.% or less, while being contained in the composition in a range of 10 to 50 pts.wt. The synthetic resin C is formed of a thermoplastic elastomer, having an MI value of 130 g/10 min or less and containing a comonomer of 30 wt.% more, while being contained in the composition in a range of 10 to 40 pts.wt.
