An object of the present invention is to provide a flame-retardant leather-like sheet base having excellent flame retardancy, a soft and high-grade feel and appearance, high abrasion resistance and peel strength, and excellent mechanical properties such as surface strength. Provision of materials and artificial leather. A layer having a flame retardant-containing elastic polymer inside an entangled nonwoven fabric of non-flame-retardant polyester ultrafine fibers (a) having a single fiber fineness of 0.5 dtex or less, and a flame retardancy of a single fiber fineness of 0.5 dtex or less A layer having a flame-retardant-containing elastic polymer inside the entangled nonwoven fabric of the polyester ultrafine fibers (b), the laminated mass ratio of the non-flame retarded polyester ultrafine fibers (a): flame retardant polyester ultrafine fibers (b) is 10: A flame-retardant leather-like sheet base material having a ratio of 90 to 90:10, and artificial leather formed therefrom.
